Strong, lightweight, sturdy, full of features!
This carabiner rocks! This is a very strong carabiner which has some very nice attributes. Even though it is a larger sized carabiner, it is lightweight for its size and has a nice smooth screw gate. The orange/red coloring to notify if you have forgotten to lock the carabiner is a nice feature. I appreciate the large opening which is helpful in several canyoneering/climbing scenarios. I primarily use my workhorse carabiners in southern Utah canyons in very rough, wet, gritty, sandy, conditions. These have held up wonderfully, and I feel like I get some of the most bang for dollar with these carabiners. These larger carabiners work well for the 4-5 tie-in points for my sandtrap anchor for canyoneering. I started out with 6 a while back, but have recently ordered 4 more. Seems like you can never have too many quality carabiners in the gear collection or in a canyon.

Solid and safe. Perfect for tying off and all safety scenarios. I love it!
Huge and lightweight locking biner
This locker is great for belay devices, anchor setups where you have multiple systems hooking into, and is very light for any multipurpose use.
Works perfectly well
This carabiner worked exactly as I expected. I used it mainly with my grigri while belaying and the gate and the screw locking mechanism works really well even after a while. My other carabiner at this point were not as smooth as the Mammut. I also really enjoy the orange marker that makes it easy to check if you're properly locked all the way in. The way this carabiner still works so well after a lot of use makes me confident it will last.
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.
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.
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.)
Well Built
Solid construction and nice and lightweight. Love the orange indicator feature. I replaced my saddle manufacturer carabiners with these, and I wish I had done it sooner.
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.
