Petzl William Ball Lock Carabiner

The Petzl William Ball Lock Carabiner is one of the best suited biners for double rope belaying, guiding, or when using a munter hitch. With a huge wide top, and large opening gate, you can get a ton of webbing, cordelette or rope inside, which is awesome for belay stations with clients or friends. The pear shape of the biner allows for belaying with a Munter Hitch on single or double ropes. The key lock nose and gate is super efficient with no snagging and makes for clipping into anything very easy and clean.
