CAMP USA HMS 2Lock Carabiner
One of the lightest lockers out there.
When is a locking carabiner lighter than most non-locking carabiners? When it’s the CAMP-USA Orbit Twist Lock Carabiner. This auto-locking biner pairs great with an auto-locking belay device, and the Orbit excels at the crags as well as it does in alpine terrain.
