FTC Fioris Ring

The FTC Fioris ring is a rigging ring for tree work, used where a smooth, round bearing surface does a better job than a carabiner: as a low-friction redirect for light lines, a connection point for slings, or a retrievable anchor component. Rings have no gate to open, so they stay closed under any orientation.

How arborists use rigging rings

A ring is the simplest piece of hardware in the kit and one of the most useful. Spliced or girth-hitched to a sling, it becomes a smooth redirect for a pull line or light rigging line with less heat and wear than running over bark. Paired with another ring, it can form part of a retrievable friction saver setup.

Rings add friction compared with a pulley, so they are better for light loads or where some friction helps. Check FTC's listed rating and use the ring with rope and slings it is designed for. Do not use it to catch heavy, falling wood unless the manufacturer rates it for that.

Rings are also easy to inspect and hard to misuse, since there is no gate to leave open or cross-load. That simplicity is why so many climbers carry a spare or two on the saddle for whatever comes up during the day.

Inspection

Look for grooves worn by rope, cracks, and sharp edges, and retire a ring with deep wear that could cut a sling or rope. See other hardware in our rings and other hardware section.

Rigging forces are dynamic and can be several times the weight of the piece. Follow the manufacturer's ratings and ANSI Z133, inspect every component before the job, and keep rigging work to trained crews.
