Screw-gate carabiner

A screw-gate carabiner in lead climbing and sports climbing is a type of carabiner with a locking mechanism. The locking mechanism is a threaded sleeve that screws onto the gate, securing it closed. This helps prevent accidental opening, enhancing safety when connecting ropes, harnesses, and gear. It is commonly used for belaying, securing anchors, and protecting climbers during ascents.

Examples

A screw-gate carabiner is a type of locking carabiner used in both lead climbing and sport climbing. In lead climbing, climbers use screw-gate carabiners to secure the rope to their harness, ensuring safety by preventing accidental opening. Climbers may attach the screw-gate carabiner to the belay device when managing a lead climb, providing an additional layer of security. In sport climbing, climbers often use screw-gate carabiners to set up anchors at the top of a route. They might clip the rope through a screw-gate carabiner to make a secure connection to fixed protection, such as bolts, especially at critical points where extra reliability is needed.
