Why We Like The Classic HMS Screwgate Carabiner

Tried and true, Mammut's Classic HMS Screwgate Carabiner is a staple in our rack. Whether we're belaying with a Munter hitch or rappelling down a canyon wall, the large, rounded rope-bearing surface lets the rope run smooth, while the bright orange indicator lets us know if we forgot to lock up.

Great screw gate with a visual to ensure closure.

Great biner with the red visual marking for extra vis to ensure it is closed. You should always check the locker but its nice to have that safety visual as well.

Great biner for belay and ancors

light weight full strength HMS biner for belaying or your master points. Indicator wears faster than one would like but this is with heavy use. Gate screws smoothly.

One of my favourite carabiners right now. I like the size of it and the colour pops out. I use it specially for my PAS and with my ATC.

Classic locking caribeaner

I use it for my personal anchor while climbing, time will tell how long the screw lasts but so far so good.

Good carabiner

Nice carabiner. Does the job really well. I especially like the orange marker on the gate to let you know of you are locked. Its a nice feature that helps double checking with just glance.

Nice carabiner

Great carabiner with nice features. Use it mostly for building anchors. Love the orange "gate unlocked" indicator, and it's a nice size for doing everything you need a basic screwgate to do. Don't love the hand feel as much as I do with some other 'biners, but I think this is super personal.
