Carabiners and Belay Devices

Locking carabiners feature a mechanism (screwgate, twist-lock, etc.) that prevents accidental opening. They’re used for belays, anchors, and any situation where security is critical. Non-locking carabiners are lighter and faster to clip, making them ideal for racking and protection.

Assisted-braking devices add an extra margin of safety by helping catch falls. They’re great for sport climbing and gyms, while tube-style devices remain lightweight, versatile, and preferred in alpine settings.

The number varies by climb. A basic kit usually includes at least two lockers (belay + anchor), several non-lockers for quickdraws or gear racking, and a personal preference for extras. Alpine or trad climbing typically requires a larger assortment.
