IronmasterUK quick-lock dumbbell half full

Ironmaster, an industry leader in sports fitness equipment, works hard to produce the best equipment for home gyms. Every piece of kit we make is hard-wearing, guaranteed to withstand all of your hard work in the gym.

This standard locking screw is part of Ironmaster’s patented Quick-Lock technology and can be used with the adjustable dumbbells or the adjustable kettlebell. It holds the weight plates in place securely and weighs 2.5 lbs (1.1 kg) by itself. This locking screw will hold up to 6 x 5 lbs (2.2 kg) weight plates and 1 x 2.5 (1.1 kg) weight plate.

“One thing I particularly liked is that the locking bolt is FLAT. Most folks will sit on the bench a minute to get pumped/concentrate before they actually lay down and start lifting…during this time they will set the weights on their upper thighs. On some of the other weight sets, this is not possible due to the end of the weights not being flat. This may seem small, but it mattered to me.” – Scott B.
