Carabiner

A carabiner is a metal connector with a spring-loaded gate used to link ropes, slings, lanyards, and hardware quickly and securely — an everyday tool for arborists, climbers, and rigging crews working at height. At Big Bear Tools, carabiner tools range from basic oval connectors to certified locking models rated for life-safety applications in tree care and rigging.

When choosing, gate type matters most: screw-gate and auto-locking carabiners offer higher security for anchor points and critical connections, while non-locking snapgates suit low-load redirects and equipment management. Always check the load rating (kN) and certification standard for your application — rigging loads, body-weight positioning, and life-safety anchors each have different requirements.
