RockLock Screwgate Carabiner is rated 4.9 out of 5 by 10.
Rated 5 out of 5 by from Way tough canyoneering biner I've used these for several years, guiding 100 days a year in southern Utah slot canyons. The ropes are often wet, and coated in uber-abrasive quartz sand that can grind a third of the way through many rappel carabiners in a single, hard day. Rocklocks last considerably longer than similarly priced competitors such as Petzl, Camp, or Trango. The metal seems harder and more resistant to grooving. So, me likeee.

Rated 5 out of 5 by from Great Guiding Biner I have been using this Carabiner for leading/guiding groups for years and they are awesome! They are perfect for belaying from above on the Munter hitch, using for belaying and are great for most everything you do when guiding.

Rated 4 out of 5 by from Seems to be a well made product. Good weight. Seems to work very smoothly.I do prefer the "Red your dead" marking system found on PETZL.

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.
