Workhorse HMS Screwgate Carabiner

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

Its size allows for user-friendly handling even with gloves. The gate opening width and volumes are large enough to accommodate multiple ropes, slings and knots.

It is ideal for use as a central carabiner for anchoring as it is particularly robust and durable.

The screw lock is easy to use even in icy or dirty environments. The keylock nose allows for easier clipping and unclipping without snagging.

An orange indicator shows that the carabiner is not closed.
