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.

My favorite big carabiner

I love mammut’s orange locking identifiers. It makes it harder to miss an unlocked carabiner for sure.

Just like the name says

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.
