What Our Customer Says

Reviewed by lifters who’ve put the QUICK-LOCK DUMBBELL SET 45 LBS (20 KG) through real workouts

    I was originally looking for a good quality bench and DB's to tie me over until the gyms opened again but then got hooked on my home gym journey and was so impressed with the quality of the Ironmaster equipment. The thought that's gone into the equipment is pure genius and totally understanding that a home gym may sometimes lack space. It's all heavy duty and the ratings on the equipment will never be exceeded in my lifetime.

  • Patented Ironmaster Quick-Lock locking screws
  • Ironmaster Lifetime Warranty
  • Storage available separately

Where should I start? Which set do I need? And how do I progress?

Most customers start with the Quick-Lock Dumbbell Set 45 lbs (20 kg)

  • The 75 lb Upgrade Kit: adds up to 30 lbs (13.6 kg) per dumbbell. Using the same locking screws as the 45 lb set (20kg).
  • The 120 lb Add-On Kit: includes four 22.5 lb plates and long locking screws
  • And the 165 lb Add-On Kit: includes four more 22.5 lb plates and extra-long locking screws

If you want to go heavier, start with the Quick-Lock Dumbbell Set 75 lbs (34 kg)

  • The 120 lb Add-On Kit: includes four 22.5 lb plates and long locking screws
  • And the 165 lb Add-On Kit: includes four more 22.5 lb plates and extra-long locking screws

The same handles work across all sets.

Do I need to buy separate screws?

Nope! Every dumbbell set and add-on kit comes with all the screws you'll ever need. No guessing required.

Is 165 lbs (74.8 kg) the heaviest these dumbbells can go?

With add-on kits, 165 lbs (74.8 kg) is the max. But if you want to lift even heavier, you might want to check out the Heavy Handle Plate Kit that adds 15 lbs (6.8 kg) to each handle, giving you extra room to grow.

How small can the weight increments be?

Weight changes can be as small as 2.5 lbs (1.1 kg) per dumbbell, so you can adjust your training without making huge 5 lbs (2.2 kg) jumps.

QUICK-LOCK DUMBBELL SET 45 LBS (20 KG)

Ironmaster Patented Quick-Lock Adjustment System

The Ironmaster Quick-Lock Dumbbell Set adjusts from 545 lbs (2.2 kg - 20 kg) per hand in 2.5 lb (1.1 kg) increments using a patented Quick-Lock screw system so you can change weights quickly and easily without fiddly spin locks or fragile plastic parts. Just slide the plates on and secure them with the locking screw. You can adjust the weight in seconds, perfect for circuits, pyramids, and everyday strength sessions.

Heavy-Duty Steel Construction

These dumbbells are built entirely from Iron and Steel, with no plastic parts that can crack or wear down over time. The chrome-plated handles provide corrosion resistance and durability, while the precision-cast plates ensure accurate weight and a balanced feel. The result is commercial-quality equipment built for a lifetime of training.

Precision Knurled Grip for Secure Lifting

Each chrome handle features a carefully machined knurled grip, giving you reliable traction even during demanding sets. The dumbbells feel balanced, solid and natural in your hands, helping you focus on form, strength, and control.

Expandable Weight System

This adjustable dumbbell set replaces an entire rack of fixed dumbbells but takes up only a small footprint in your home gym. Unlike many adjustable dumbbells that cap your progress, the Quick-Lock system is fully expandable.
You can increase the maximum weight using optional expansion kits. Upgrade from 45 lbs (20 kg) to:
- Standard expansion up to 75 lbs (34 kg)
- 120 lb add-on kit (54.4 kg)
- 165 lb add-on kit (74.8 kg)
No need to replace your equipment, just grow with it. The Ironmaster Adjustable Dumbbell set is a long-term investment in your progressive strength training.

Compatible with the Quick-Lock Ecosystem

The weight plates and locking screws are compatible with other Ironmaster Quick-Lock equipment, including:

- Quick-Lock Adjustable Kettlebell
- EZ Curl Bar
- Straight Bar

Your equipment works together seamlessly, saving space and giving you more training options.
