RockLock Screwgate Carabiner is rated 4.8 out of 5 by 12.
Rated 3 out of 5 by from no change in 20 years Im sure this biner is strong & solid but (ordered online sight unseen) its really fat (in diameter). its the exact same 'biner as I already had from 20 years ago. I needed one that fit through the rappel/hardware chains of most modern stations. this one does not, or when it does its a wedged fit. Im disappointed that BD has not seemed to keep up with a better selection of small framed light carabiners.

Rated 5 out of 5 by from Great biner for everything I like this for both belaying and anchors so I probably own like six or eight of these. I like the large size and trust BD so I think these are a biner everyone should have some of.

Rated 5 out of 5 by from It's the workhorse of carabiners! The RockLock Screwgate Carabiner is lightweight, tough, easy to operate, and an overall great locker for canyoneering and climbing. I have several of these for building anchors, belaying, and other purposes. Sure, there are fancier carabiners on the market, but RockLock gets the job done and works great, and that's good enough for me.

Rated 5 out of 5 by from Rock Solid/ Lightweight This locker is always attached to my belay device. Because of the roundness it make for a very smooth rappel. Much better than the other lightweight lockers out there, there are no ridges to add friction. Great size for use with a Munter. I really like this one. I choose a screw gate because they work well in the cold, snow and ice. You never have to fumble with it or take your gloves off.
