Carabiners & Connectors

Carabiners for Tree Work

Carabiners are essential for tree work. According to the ANSI Z133 standard for Arboriculture Operations, carabiners in a climbing system must be self-closing and self-double-locking, and have a breaking strength of at least 5,000 lb (25 kN). See "Double-Locking" carabiners for carabiners that meet this standard. Accessory carabiners are handy for racking gear on your climbing harness, and screw-locking carabiners have rigging applications.

Double-Locking Carabiners: self-closing & self-double-locking, with at least 5,000 lb. MBS. This meets the ANSI Z133 standard for connector that will support a climber. You may hear these carabiners called auto locking or positive-locking.

Screw-Locking Carabiners: perfect for rigging and setting up redirects. A screw-locking gate is not approved for the primary support of a climber in tree work.

Non-Locking carabiners: come in all shapes and sizes, from large paddle carabiners perfect for racking a saw, to tiny accessory 'biners to tend an SRS system.

ANSI Gate Carabiners: these locking carabiners meet the ANSI z359.1 standard for fall-arrest connections, with a MBS of at least 16kN strength on all axes, even side-loaded.

Steel Carabiners: increase strength and durability along with weight. Many uses in rescue and rigging.

Carabiner Keepers: keep your hardware positioned correctly on slings, lanyards, and more.
