The Kettlebell is a great tool for sports training, fitness and strength.
The Ironmaster Quick Lock Kettlebell Handle saves both money and space, and provides a huge range of Kettlebell weights.
The QLKB weighs 22.5 lbs empty and will accept the Quick-Lock Dumbbell weight plates and uses the same locking screws. This makes it a great accessory to expand the capabilities of  adjustable dumbbells.
The standard locking screws will provide up to 57.5 lb KB weight,  and with the Add on Kit locking screws you can go up to 80 lbs KB weight.
The handle is big enough for two handed use, but shaped well for single hand. The handle is made of formed steel specially cast  into the base for extra strength. The locking threads are machined steel – the same as on the Quick Lock Dumbbell Handles so everything is heavy duty. The shape and ergonomics designed into this KB took a long time to get right through many hours of testing. The locking screw will not interfere with your grip. The QLKB is sold as a single handle.
