Built for Safer, More Stable Belaying
When you're belaying, every piece of gear matters. The Mountain Rocks HMS Locking Belay Carabiner is designed to keep your belay system stable, secure, and easy to manage, whether you're climbing indoors or outdoors.
Its wide HMS pear shape allows smooth rope handling with belay devices, while the integrated captive pin helps keep the carabiner correctly oriented on the belay loop. This reduces unwanted rotation and cross-loading so you can focus on the climb, not your gear.
Lightweight, durable, and certified to international safety standards, this is a carabiner you can trust session after session.
