Heavy Handle Plate Kit for the Quick-Lock Dumbbell Handles

This kit has been developed to increase the weight range of our adjustable dumbbells. 2 piece plates fit on the inside of the handles against the backing plates. Still enough room for handgrip and is perfectly balanced. Most people rarely use less than 20 lb dumbbells so having a higher weight range that starts at 20 lbs is ideal. Now your 5-75 lb dumbbells can become 20-90 lbs! Or a 5-45 lbs set can become 20-60 lbs. Or you can even use this to add even more weight to dumbbells and the add on kit. 5-120 lb set can become 20-135! See below for pics and more details.

Note: Fat grip adapters will not fit with this kit in use. Inside grip space with the HH plates installed is about 5.18″

Note: The width of these plates in the same as current QLDB production plates which is about 1/8″ wider than older plates made prior to 2015/2016 when we used a different foundry. Use with older QLDBs is still possible but will require a bit of effort to align the locking screw when making weight changes. Standing the dumbbell on end can help. Please contact us if any questions.

Expands Load Capacity, Not the Size

Designed to expand the capacity of your QLDB, these four additional handle plates bolt on the inside of the dumbbells against the backing plates, adding 15lbs to each dumbbell.

  1. Two pieces of 7.5lb-plates fit around the handles on the inside of each dumbbell, resulting in a total of 20lbs starting weight.
  2. Adds 15lbs to each Quick-Lock adjustable dumbbell making your 5-45 lb dumbbell set weigh 20-60 lbs. The 5-75 lb set becomes 20-90 lbs and your 5-120 lbs are amplified to 20-135 lbs.
  3. The new weight range this creates can be perfectly suited for many Ironmaster trainers who rarely go below 20 lbs anyway.
  4. Since these plates are placed on the inside of the dumbbell handles, your dumbbell will not increase in size, only the weight.

Spacious and Improves Weight Balance

Despite adding these heavy plates between the two backing plates on your dumbbell handle, there’s still enough space on the handle for you to grip comfortably. You can also expect a better weight balance because these plates are placed closer to the dumbbell’s center of gravity.

  1. Leaves a 5-inch grip space for holding the dumbbell.
  2. Better weight balance is established as the center becomes heavier.

Safe, Secure and Well-Crafted

The heavy handle plates stay in place by means of strong large screws that hold them together around the handles. Manufactured from powder-coated and precision-machined cast iron, you can be sure these plates will last a lifetime.

  1. The plates will not move or get dislodged once they are securely attached to the handles.
  2. The two halves of the plates are securely clamped and tightened around the handles using the two heavy-duty machine bolts and will never move.
  3. The plates are precision-machined from solid cast iron with black powder coating finish.

The 2 piece plates fit on the insides of the dumbbell handles like this. 20 lbs as pictured.

*The two halves clamp down on the round handle very securely and will not twist or move

once the two large machine bolts are tightened.*

5-45 lb dumbbell becomes 20-60 lbs as pictured.

5-75 lb dumbbell becomes 20-90 lbs as pictured.

5-120 lb dumbbell becomes 20-135 lbs as pictured.

Still plenty of grip room with more than 5″ space. In fact, the dumbbells become better balanced with the weight closer to the center!

Note: Fat Grip Adapters won’t fit around the handle once the Heavy Handle Plates are attached.

  1. This new weight add on is just what I needed to get my dumbbells heavier but not the full add on kit. Won’t have to switch pins to go up to 80 or 90 and that is enough for now. I actually like the feel of the handles better with these plates. Seems to lock on nice and tight. Thanks Ironmaster!

  2. Got my heavy handle kit, love the feel. Weight feels so much more secure closer to my hand when going heavy. Bought a set of the 2.25 fat gripz to use as well, fit just right.

  3. Adds a greater ranger for my current setup. Really do enjoy the shortened handle. Well balanced. After checking off and on for the past few months was definitely excited to see they restocked. Couldn’t be happier.

  4. I had the 75lb DB set with the 120 add-on kit and I snatched up the Heavy Handle Kit as soon as it became available. This gives me a 20-135lb/hand set. An entire rack of DBs in this range would use a ton of space and cost several thousands of dollars, With the Ironmasters, it takes a fraction of the space at a great price and you aren’t sacrificing anything as these have the quality feel of a regular, fixed weight dumbbell. As other reviews have mentioned, with the kit the DBs are more compact, balanced and easier to control especially once you’re pushing over 70lb. Be aware that with the heavy handle kit that the smallest DBs you can have are 20lb unless you remove the kit, which I wouldn’t plan on doing. So if you regularly use 10 or 15 pounders then you may avoid this product or buy a pair of fixed weight 10’s and 15’s. Great value if you want a simple and inexpensive way to increase the top range of your Ironmasters.

  5. Just got these and I have to say they are awesome. They make the dumbbells feel much more balanced and compact. Do not hesitate on these.

  6. Very nice, does what it’s suppose to. You can actually put both pairs on one dumbbell and it literally becomes the worlds most compact adjustable dumbbell which no other dumbbell can brag about. My 50lb dumbbells don’t look like 50lb dumbbells anymore and now there’s more range in motion for me.

    Looks a bit bare with the plates on. The 7.5lb markings probably should have been on the otherside so that it actually shows? Or at the very least, include a nice IRONMASTER decal/sticker to put on the plate so there’s an up-to-date kind of look.

    Functionality, it seems very tight. Doesn’t look like it’s going to loosen any time soon but only time will tell. Other than that, I can see this product lasting a helluva long time.

  7. I just bought these and they are already my favorite purchase from this site. Like mentioned elsewhere, they do bring the center of gravity inward, resulting in a more secure feel, but what I also love is how much simpler they make operating the whole system. 35lbs on the stock QLDB is a 6-plate system, but with these handles its only 1 plate per side. By the time you add more than 2 plates/side, you’re already taking your QLDBs into the 45-60lb “bonus range” this add on kit provides. Great value.

  8. Super easy to install, and lots of hand room left over at 5’11” tall. My dumbbells now range from a rock solid 20 LBS to 180 LBS. I have an extra pair of tiny 10 LB dumbbells to complete the bottom range that I may use from time to time. A++

  9. Very easy to install. Does exactly what it says(adds more balance). I honestly feel like its a must have for any personal trainers or any ironmaster dumb bell owner, as the regular ironmaster dumb bell handles are a bit more suited for the experienced lifters.

  10. Quite simply, the best addition that you can buy for the QLDB system. The tension system works perfectly to keep them in place and the handle seems (to me) far more comfortable and balanced with it on. I don’t anticipate taking them off again. I’d rather get a second set of handles and add the fat grips to them.

  11. The ironmaster adjustable dumbbells are simply the best available, but the grip space is a bit too wide which can make the handles tougher to balance and bulkier than other cast-iron or rubber hex dumbbells.

    The heavy handle kit completely fixed this issue and is an absolute must in my mind.

    Some people look at the price vs the weight and say it is too expensive, but that completely misses the functionality improvement.

    The dumbbells are much better balanced with the heavy handle kit, particularly noticeable for pressing, and it makes the dumbbell more compact for the same amount of weight. You can also now get to 90lbs with the standard 75lbs kit, which is pretty heavy especially for the compactness.

    Still have ample grip space for your hands.

  12. Great addition to my QLDs, easy to install and bombproof so far. Most of the other reviews state that dumbbells are now much better balanced with the heavy handle kit, more compact for the same amount of weight… I totally agree, DBs much more functional now. I purchased my QLDB set in 2010 and have used them few times/week for the last 10 yrs without any issues… exceptional product, I wish i purchased my heavy handle kit sooner, worth the expense

  13. Heavy Handle Plate Kit Review
    These are the best add-ons to the quick lock dumbbell system. I purchased these back in February even before getting the QLDB since I was waiting to be selected for the lottery. After reading reviews and watching YouTube I decided I needed to buy these as soon as it was available. The craftsmanship, packaging, and setup is fantastic. IronMaster’s attention to detail is superb. This helps balance the dumbbell to be more centered in gravity. This turns the dumbbell into a starting point of 20lbs without locking screws. This also brings in the handle width down to 5 which is equivalent to standard dumbbells. If you have the QLDB system or considering getting one, please be sure to add these to cart as well. Quite possibly the best dumbbells I’ve used and would highly recommend to all my friends and family. 10/10 Simply Perfect.

  14. Heavy Handle Plate Kit Review
    I received these last week but today was the first time using it and used the hell out of it. I’ve been an owner of the ironmaster DBs for almost 8 years now. With this heavy handle kit they feel like brand new DBs. Like every review says they make the weight far more centered and balanced. This might now be the most compact DB on the market. Also my fatgripz and iron bull strength grips fit perfectly on it. Another great product by IM and surely does not disappoint. Well worth it!

  15. Love the weight closer
    I bought these when they were first released because I loved the idea of the weight being closer to my hand. Two or three years later I see someone comment about combining both sets on one handle. I may hve to try this out on one dumbbell to see if it works for my hand. If so I may order again. Just the one set feels a lot more comfortable on the wrist.

  16. Perfect upgrade
    These are a perfect upgrade to the standard DBs. Makes setting up typical weights much easier, and frees up plates for other exercises.

  20. No Brainer
    If you’re okay with the lowest weight being 20lbs, then this upgrade is a no brainer. Not only does it set a more reasonable weight baseline, it improves the balance and the feel of the dumbells and increases the maximum weight. I’d only advise not getting these if you regularly want to work with sub-20lbs since removing the attachments is not something you’d want to do regularly.

  21. I have had the heavy handles for about two weeks. I wanted more than the 75 pound max of my dumbbells but did not need to go all the way up the 120 pound add on kit. My experience has been similar to other reviewers. The heavy handles improved the feel of the dumbbells and have remained secure so far. I would highly recommend if you need a little extra weight or just to improve the feel of the dumbbells.

  23. Perfect to more perfect!
    These weights add the weight and comfort that take these dumbbells to the top of the list. They are balanced, cozier, and smoother. I’m big, 6’3” 275lbs. And have thick hands. I still have plenty of space and play when using these. Installing them the same way all 4 times with the bolts facing up also gives a nice additional visual to have the correct orientation with the notches, helping to make weight changing easier. Having 90lbs dumbbells now instead of 75lbs also makes these a stronger contender. It also helped to tighten each to the same amount of turns. Keeping them even with the handles. Good stuff.

  24. This is a brilliant design. Prior to buying these, I had their 75 lb adjustable DB’s. The best benefit in my opinion is the balance this addition offers to the overall feel of the dumbbells. Their DB’s feel great either way but these make them feel a bit more like a traditional DB by centering the weight distribution. They do not move around at all. I’ve used them 3-4x/week in my training for the past 1-2 months since adding the heavy handle kit and have not had to make any adjustments or tighten them. Perfect design. Highly recommend.

  25. really makes a difference
    Easy to install and makes the dumbbell feel more compact and balanced. Love that I can go up to 90lbs now.

  26. Added these to my IM DBs last month, easy to fit and remain solidly in place, the reduced space on the DB handle and the plates being inside makes the DBs feel more balanced in use.

  27. A needed upgrade
    If you do not lift weights less than 20 pounds, then this is a must have. It is extremely sturdy, looks good, and feels good while using them. Installation was simple. I’m very glad I bought these.

  28. Really perfects the dumbbells
    I bought these at the same time I ordered the dumbbell kit. Based on the reviews, it shortens the handle length and gives for a more natural grip. I couldn’t agree more! The dumbbells feel exactly the same as any regular dumbbell with these. It also adds 15lbs to your setup so instead of 75lbs, I get 90lbs per dumbbell. Zero plate weight is 25lbs with the heavy handle kit. If you need lighter dumbbells, Costco has Inspire Fitness rubber dumbbells from 5-30 lbs for $299 in some stores. That, along with the Ironmaster’s and this heavy handle kit completes my dumbbell set and should be good to go for you as well. This kit really perfects the grip of the dumbbells.

  29. Excellent kit. I prefer the width of the handle with this addition. I put the bolt heads to line up with the arrow making it even easier to see the release side. That extra 15lb max/90lb dumbbells is great. You also don’t have to add as many 5lb plates since you’re starting at 20lb. You do lose the lower weights is the one downside.

    5 out of 5
  30. almost perfect. If they want a better product they can round the inside edges a bit. It may not be an issue for smaller hands and smaller people but my wrists touch the edges if I bend them just a little when using these (hands are centered inside the open space). It’s not going to stop me from using them, they are a pretty awesome addition for some extra weight. My set currently goes to 135 and that is enough for now. I don’t use gloves when lifting but that will fix any potential issue with my wrists touching the edges of these when lifting. I would recommend these to anyone that can lift over 30 lbs. Silver lining is I can just train myself to keep my hands aligned better so still a win.

  31. Must have for your Ironmaster dumbbells. Better balance and feels like standard dumbbells.

  32. Significant improvement.
    This plate kit really improves the dumbells overall. As long as you’re ok losing the 5-15 lb range, it’s a great upgrade. It improves the balance of the dumbells, reduces the number of plates needed, and increases the maximum weight.

  33. Super easy to install they give the handles a closer grip. Ironmaster products are the best. Thank you ironmaster for your good customer service and products.

  34. These are a must if you have the DBs because they greatly improve the balance and feel in addition to upping the total weight.

    There is still plenty of space for your hands, but I would rather have the plates be 5 lbs each so the minimum DB weight is 15 lbs rather then 20 lbs. Gaining that flexibility is more valuable to me because I also have the 120 lb add-on kit.

  35. Iv’e read all the reviews and can’t say it any better, these plates are the perfect addition to my 75lb DB set. Thank you for making them available!

  36. Received the heavy handle kit the other day. Thank you for shipping it out to me so quickly. The kit gives the dumbbells a completely different feel, and I love the aesthetics. It’s a huge win for both Ironmaster and those of us who have the dumbbells. The kit solidifies IM dumbbells as a permanent part of my workout routine. Have a great week!

  37. Nice increase.
    This is an affordable first step to increasing your weight set and is a must with the 75lb set.

  38. I’ve had the Ironmaster adjustable dumbbells for quite a while, and the one thing that always bothered me was doing bench with them. Just due to how far out the weight was when going heavy, it made stabilizing them quite difficult (for me).

    After adding on the heavy handle kit, the weight is significantly more closer to center, the dumbbells feel a lot more balanced and easy to control, and feels just miles better.

    10/10, best upgrade

  39. The addition of the heavy handles have been well worth it. Not only do they allow you to add extra weight. They balance out the dumbbell very well. Highly recommend. Leave plenty of room for hands as well. No issue there.

  40. Great addition to an already great product

    Like all good tools, a bit pricey but worth it.

    Ironmaster dumbbells are the bomb, and these extra weights give them extra firepower.

    Nicely machined and great fit.

  41. I’ve had my IM dumbbells for a long time, so I am very accustomed to the feel and function of this product. But as we all know, the handle is long and fully loaded the dumbbell length is also long. The folks over at IM keep innovating and bringing great products to market, and the heavy handle kit really delivers, imo. It shortens the handle length and makes the dumbbell more compact. If you’re a long time IM dumbbell user, this kit takes some getting used to. At lower weights, it feels amazing. But as you progress towards heavier weights, it takes time to accustom yourself to the decreased handle length, because it does substantially affect the dynamics of how the dumbbell balances during the concentric/eccentric phases of the lifting cycle. Give yourself time to adjust, and in my experience with the kit added the IM dumbbells become an overall better, more enjoyable experience.
