Tough but relaxed.

The Mad Rock Ultra Tech Twist-Lock Carabiner rarely gets bent out of shape. In fact, thanks to humongous strength ratings, it would take a lot to bend this locking biner at all. If you want the convenience and safety of twist-lock without the extra weight, fret not: the Ultra Tech weighs in at a slim 57 grams.

I bought this go with the Mad Rock Mad Lock; it works OK but not great. I generally don't like twist locks and this one is no different; after a couple of uses I can already feel sand in the lock and can't clear it. Not really big enough for more than one clove hitch, and not light enough to warrant the drawbacks. Stick with the BD Mini-Pearabiner.

i like these things

i'm a pretty big fan of these little guys. i haven't been using them long enough to really give much of a report on durability. they do seem solid though. i've so far used them with mostly a 10.2 rope and it's worked out fine for me so far. i'll update if i have any problems with these.

Just used 5 times max

i got these carabiner to give a second chance to mad rock carabier`s but a gain i am super disappointed, i only got to use it about 5 times on multy ptch climbs and it did a god job but the las time maybe some dirt got in and the Twist lock stopped working correctly, i tried to clean it and lubricated but no luck with that, and its not the firs time im disappointed with Mad rock equipment. now i only use it to carry my day bottle.

ultra locker

feels super solid
no way this thing is accidentally opening

not easy to open with one hand
gate is a little small for inserting rope when used with an ATC (especially when double rope repelling)

Responded on

this biner is not meant for rappeling or belaying. it is not rated HMS which is what belay niners are rated for! thats why its so small!
