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.

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.

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

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.
