Thet FTC Donut is a blend of a rigging block and friction ring. Use the sheave to lift or move a load, or use the center for added friction while rigging. Need both at once? The DONUT can run two ropes simultaneously to manage complex situations, including heavy loads or controlled load transfers.

Friction is critical in tree rigging. It reduces effort on the cylinder and helps the ground worker control descent speed. More control improves safety for the climber and crew by minimizing the risk of sudden or uncontrolled movement.

The DONUT's round shape helps prevent incorrect positioning and reduces the risk of overhanging. It is easy to set up, including between two axes. Its symmetrical design also works well with multiple slings, making it easier to dial in precise placement. Use it on the ground (for example, as a redirect) or in the tree.
