Karabiner for Safety Harness

Karabiner is a specialized type of shackle, a metal loop with a springloaded gate used to quickly and reversibly connect components, most notably in safety-critical systems. Karabiners are vital for climbers and mountaineers to keep various pieces of equipment connected to each other, and thus to keep themselves safe while they’re climbing. A Karabiner can take various forms and shapes, but it’s usually a metal oval, with a spring-loaded clip that stays closed unless it’s pushed open.
