Mammut Workhorse HMS Screwgate Carabiner

The Workhorse Screwgate carabiner is the strongest Mammut carabiner and one of the most robust models on the market.

An easy-to-operate carabiner, the Workhouse HMS Screwgate has a screw-locking closure which is usable in all weather and conditions. The opening width and volumes are large enough to accommodate several ropes, slings and knots and its size allows user-friendly operation even when wearing gloves. It is ideal for use as a central carabiner for anchoring as it is particularly robust and durable. The key lock nose allows easier clipping and unclipping without snagging. An orange marking indicates when the carabiner is not closed. The design has been optimised for smooth belaying and high service life.
