The Yellow Square 3D00012 is a thick black cylinder handle, 5 cm in diameter and 14 cm tall, for grip and wrist flexor training in armwrestling. The fingers cannot fully close around it, so the grip and the wrist work together. It attaches through a 14 mm hole and is 3D printed in Ukraine from engineering plastic.

Who it is for
Armwrestlers whose grip gives out before the wrist, and anyone who wants to build the wrist flexors with a thick handle. Experienced athletes can use it as the next step after slimmer cylinders.
Who should skip it
Beginners with no thick-handle experience: holding heavy weight on a 5 cm cylinder is hard, and wrist training will be limited by finger strength.
Use and compatibility
Uses: grip and wrist flexor training for armwrestling, on a cable or with free weight as the description states. No compatible equipment list is given, so choose an attachment that fits the 14 mm hole.
What is in the box
One black 3D00012 cylinder handle. Carabiners and cables are not mentioned in the description.
