Carabiners have a thousand and one uses for the professional tree climber, and when combined with daisy chains, swivels, rigging plates, and other accessories, the possibilities just get better. The tools on this page will help you get more functionality, improved performance, and new tricks out of your carabiners and climbing gear. You will also find a wide range of round, tear-drop, plastic, and metal thimbles for use with your carabiners and rope clips to help preserve the strength of your climbing line.

A note on hardware testing: Our rings are individually proof-loaded to 60% of published minimum breaking strength of 5,000 lb. This means each ring is loaded to 3,000 lb. before it leaves the factory. In addition, they are batch tested to destruction, which means that several units of every batch are loaded until failure, and if any break under 5000 lb, the whole batch is scrapped.
High density plastic roller is used on with the Petzl William carabiner to create an almost frictionless attachment point on the Versatile or Deluxe Versatile saddle. Carabiner clips through roller and then rolls along bridge.
Stainless steel wire corner traps snug over your carabiner to ensure that your rope stays in the proper position and prevent the carabiner from slipping into a position where it might be side-loaded.

Metal rings are great for customizing your gear. We carry aluminum and steel rings in several sizes so that you can make custom friction savers with rope or nylon webbing, add a sliding ring to the rope bridge of your saddle, and more.
