Mammut Workhorse HMS Screwgate Carabiner

The Workhorse HMS Screwgate carabiner from Mammut is the ultimate companion for demanding mountaineers and climbers. As our largest and most powerful locking carabiner, it offers an impressive breaking strength of 27 kN lengthwise, 8 kN open and 12 kN crosswise, making it one of the most robust carabiners on the market. Its optimized design ensures smooth belaying and a long service life, even under extreme conditions.
Particularly noteworthy is the orange marking that immediately warns you if the carabiner is not securely fastened. This significantly increases safety when climbing. Thanks to the keylock nose, it is easy to clip in and out without getting caught, which makes the carabiner ideal for use in complex belay situations. The screwgate is easy to operate even in dirty or icy environments, which underlines its versatility and reliability.
Weighing just 75 g, the carabiner is light enough to carry easily on long tours, but still offers the necessary stability for demanding climbing activities. The generous opening width allows the handling of multiple ropes, slings and knots, making it the perfect choice as a central carabiner for anchoring.
