Ultra Tech Twist-Lock Carabiner

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.

Gets the Job Done

I've used it several times

Good Carabiner for locking in. Twist lock does take an extra second to lock but works fine.

Good for the price.

I've used it several times

Gets the job done that's for sure. Not the best one out their but for the price point it's a great product. I have two and like them pretty good if your looking for a good twist lock and are on a budget this is a fair product for the money.

It Works

I've used it once or twice and have initial impressions

Not much to write home about. It works and gets the job done. Got this as a gift. Don't know if I would seek it out, but I am pretty happy with it.

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

pros feels super solid no way this thing is accidentally opening cons 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)

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!

Doesn't HMS refer more specifically to being rated for a munter hitch? Just out of curiosity, it there really any problem with using a non-HMS locking biner for belaying, as long as everything runs smoothly and the device brakes well? I have been using one of these as my primary belay 'biner for the past year or so because it works smoothly with my mega jul (a device which can be finicky in conjunction with some 'biners and different types of ropes). I also very much like to use an autolocker as my belay 'biner, as it's one of the few non-redundant and human-error prone parts of the system. Of course I still check every time to make sure it's actually locked.
