The Black Diamond Airlock Carabiner is a large yet light HMS carabiner that is perfect for belaying and also rigging belays. This combination of weight and flexibility make it one of the best all round screwgates on the market today.

The large 22mm gate opening allows for quick attachment of knots and hitches and the large internal volume ensures that there is plenty of space for two or more ropes. An Airlock on any trad' climbers rack is sure to prove invaluable and see plenty of action.
