Why We Like The Workhorse HMS Screwgate Carabiner

Mammut's strongest 'biner, the Workhorse HMS Screwgate takes on heavy loads. With the larger mouth able to accommodate multiple ropes, slings, and knots, this 'biner is our go-to center for anchors, while the bright open indicator makes sure we never forget to lock it up.

Just like the name says

I really like this carabiner and especially the visible cue that it is locked.

Might be my all time favorite locking HMS. It has a massive basket and is surprisingly light. These are my go to for anchors.

Un peu gros, mais utile

Mousqueton un peu gros, j'en ai commandé 4 sans avoir vu la grosseur. Très utile pour les multi pour se "longer" à plusieurs en cabestan où pour mettre au bout d'un longe, sa largeur facilite le placement dans les ancrages fixes de toutes sortes (scellement, plaquettes, chaînes, anneau, etc.)

Great locker for anchors. When you build a complicated anchor where you need to clip several slings/cords together, then this locker is the choice.

Normally I use steel carabiners for setting up top ropes because of how durable they are. However, these carabiners have proven just as durable and significantly lighter. Whether you're setting up top ropes, clove hitching in on a multi pitch, or rappelling or belaying, these carabiners are a must have.

I cannot recommend the MAMMUT Workhorse HMS Screwgate Carabiner highly enough! This piece of gear is an absolute workhorse in every sense of the word. The build quality is exceptional, with rugged and durable materials that stand up to heavy use and abuse. The screwgate mechanism is incredibly secure and easy to operate, providing peace of mind when using it in even the most demanding situations. I particularly love the large size and shape of this carabiner, which makes it incredibly versatile for a wide range of uses, from belaying to rigging and beyond. It's also surprisingly lightweight for its size, making it easy to carry in my pack or harness without adding unnecessary weight. Overall, the MAMMUT Workhorse HMS Screwgate Carabiner is an outstanding piece of gear that I would not hesitate to recommend to anyone who needs a reliable and durable carabiner for their adventures.

Great caribiner

Solid, auto locking caribiner. Perfect paired with the Mammut tube-style belay device.
