The BLK BOX Rubber Hex Dumbbell is a cast iron dumbbell with vulcanised rubber-encased hex heads and a chrome-plated knurled handle. It is sold as a single dumbbell and runs from 2.5 kg to 60 kg in 2.5 kg steps, with a 25 mm handle on the lighter sizes and 35 mm on 15 kg and up. The hex head stops it rolling and the rubber damps noise and protects floors, which makes it a fit for home, garage and commercial gyms. Against fixed-weight rivals it offers a wide weight ladder and embossed markings, but buyers pay per dumbbell, so pairs cost double.

Rated 4.8 out of 5 from 682 ratings, owners are largely positive. They like the build, the knurled grip and the rubber heads that protect floors. The main friction is the per-dumbbell sale and the factory coating.
The BLK BOX Rubber Hex Dumbbell has a cast iron core with vulcanised rubber-encased hex heads and a chrome-plated knurled handle. It is sold individually, one dumbbell per purchase, in weights from 2.5 kg to 60 kg in 2.5 kg increments.
The hex shape stops the dumbbell from rolling. The rubber heads reduce noise and protect flooring. Weight markings are embossed.
It is used for presses, rows, curls, lunges, squats, carries and floor-based exercises. It suits strength training, muscle building and functional training in home gyms, garage gyms, commercial facilities, and elite sport and high-performance facilities. It arrives coated in a protective lubricant, so wipe it down before use to prevent floor markings.
