Mammut Workhorse HMS Screwgate Carabiner

The Workhorse HMS Screwgate Carabiner from Mammut is the manufacturer's strongest carabiner and one of the most robust options on the market. Its generous size allows for easy handling even with gloves and offers enough space for multiple ropes, slings and knots. This makes it ideal as a central carabiner when anchoring.

The screw cap works reliably even in dirty or icy environments and is complemented by an orange marking that indicates when the carabiner is not fully closed. The keylock nose also ensures easy hooking and unhooking without snagging, which further increases safety and ease of use.
