This was my primary belay carabiner until I discovered the Gridlock. Mine is the screwgate rather than the twistlock.
--It's huge; if it can't fit what you need to feed through it you should probably reconsider what you're hanging off your carabiners.
--Solid, smooth, reliable gate action and a locking sleeve that resists the sandy goodness found at so many crags.
--Super smooth belaying.
--Easy to slide ropes, hitches, runners, etc., around the spine thanks to a smooth profile.
--It's quite large. So large that it can be a liability at space-tight anchor bolts. For those I prefer the Positron Screwgate.
Overall a great carabiner. Between this and the Positron locking 'biner there's not much you can't do.
For the price, you can't beat this biner for what it brings to the table. The screwgate spins cleanly and its a sturdy beast.
That said, it is relatively easy to crossload while on belay if you aren't watching your gear, especially on routes that create slack then create loads. I have also had the screwgate loosen on me once as well, so now I make sure to torque it down before giving the thumbs up.
Overall pretty good, could definitely do worse.
These biners are the standard. I use them for anchors, belays, whitewater taglines, live-bait rescue tethers, even carrying my keys when I have to retire one. Don't expect it to excel at anything, they weren't built for that. They were made to be the majority of lockers on your rack, not all of the lockers. They are great, inexpensive biners for setting up systems and no rack is complete without a dozen.
Wayyy better then the triact-lock biner or any with a 3-point lock system! Easy to open and good size. Usually it's kept on my harness as a belay biner but could be used on directs, I don't just for added safety. Strong, reliable, big gate, good size. Overall my favorite twistlock bener out there
If you are looking for an all around good locker then look no further. For the price this locker is fairly good. No complaints yet with it but then again I usually just use it for an anchor so I don't get to see it in action all that often.
If you want an extremely useful, just the right right size, relatively cheap, and one you continue to buy time after time, buy this locking carabiner.
The size is great, big enough to clip multiple things for multipitch and light enough to bring a second.
Can't beat it.
This carabiner has a very nice smooth gate action with just the right amount of tension. The screwgate works flawlessly. I have enjoyed using it and haven?t looked back since adding it to the rack! Great for setting up belay or anchor system.
greast carabiner to use as the center point of the belay station, or to use with and ATC or reverso as the round edges helo the rope move better
not the lightest, not the heviest
I've been using this biner for many years and Is always my go do to locking biner. It is affordable and dependable! Get it know while it is on sale!
Locking is smooth and easy to open/close. Bought this with the screw gate for belaying. It has lots of room and works great. Good value too!
Big locking biner. Use them exclusively for top rope anchors due to how cumbersome they are. Would not use them for much else.
