Screw Locking Carabiners
Screw-gate carabiners are a favorite of many tree climbers. Screw gate carabiners are very popular for rigging, redirects, and other operations. We stock many styles of carabiner, from standard D shapes to large mouth carabiners, and also captive and swivel eye models from companies such as Petzl, Kong, Spider, and CMI. Steel carabiners give you the highest strength but also are considerably heavier than aluminum carabiners. Aluminum locking carabiners are by far the most popular, and we have many styles for you to choose from.
