A tough forged steel ring for building ring slings, anchors and redirects.
A forged steel rigging ring is a solid ring that tree crews splice or girth into slings to build anchors, redirects and adjustable rigging points. Steel stands up to the wear and abuse of rigging rope running across it day after day.
Rings are a simple, strong way to build adjustable anchors. Splice one onto a sling, or pair two rings for a ring-and-ring false crotch. In rigging, rope runs through and across rings constantly, so a forged steel ring holds up better than aluminum when you are lowering wood all day.
Make sure the ring is large enough for the rope and hardware you plan to pass through it, and smooth enough to avoid cutting rope fibers.
Rings also let you change rope direction without the friction and wear that come from running rope directly over bark.
Choose a ring with a working load limit suited to your rigging, allowing for the high forces created when wood is dropped or swung onto a rigging point. Check the marking or listing for its rated strength and do not exceed it.
Inspect rings for nicks, burrs, grooves worn by rope, cracks and deformation before each use, and retire any ring that is damaged. More hardware is in our rings section.
Keep rigging rings separate from climbing hardware so they never end up in a life-support system by mistake.
Clean sap and grit off rings after each job, since grit embedded in a ring will wear rope faster.

Only if it is rated and marked for life support. Otherwise keep rigging rings for rigging.
Steel resists the wear from rope running over it and from rough handling better than aluminum.
