What is a carabiner in rock climbing?
Carabiners are typically oval loops of metal with one side that
opens referred to as a "gate." They have a variety of uses in
climbing. Locking carabiners, with a gate that closes with another
metallic portion to lock shut, are used primarily to belay, to set
up anchoring systems, and to do work on climbing walls. Non -ocking
carabiners are what's used for quickdraw protection for lead
climbing, hauling gear, attaching gear to your harness or pack for
transport, and other functions where bodily safety is not at
stake.
