DONUT FTC – Rigging Block and Friction Ring for Tree Rigging

Description DONUT FTC – Rigging Block and Friction Ring for Tree Rigging The DONUT by FTC is a groundbreaking tool in professional arboriculture and rigging: a unique fusion between a rigging block and a friction ring in a single versatile and reliable device. Thanks to its round shape and dual functionality, the DONUT lets you choose whether to use the sheave to lift or move a load, or the central part to generate the friction needed during rigging operations. Its structure also allows the simultaneous use of two ropes, making it ideal for complex situations such as heavy loads or delicate load transfers. Friction is a vital element in dynamic rigging: it reduces the effort on the cylinder and allows the ground operator to precisely control the speed of descent, contributing to the climber’s safety and that of the entire team. The round shape minimises the risk of incorrect positioning and simplifies setup, even between two anchor points. The symmetry of the DONUT also allows use with multiple slings for even more precise placement. Perfect for: Static and dynamic rigging operations Lifting and moving loads at height Use as a redirect on the ground or up in the tree Double rope configurations Professional arboriculture and delicate load management Developed directly from field feedback, the DONUT embodies the FTC TREE philosophy: a reliable tool, adapted to all constraints without overcomplicating the work. Versatile, robust, safe.
