Great biner. i exploit this with the Mad Rock airman (belay device) and a ten.2 geographic area rope and it's worked excellent on behalf of me. when victimisation it double every week for a few month the coating/paint has worn off on the within from the rope rubbing against it (while belaying). a straightforward aesthetic issue that does not trouble Pine Tree State in the slightest degree. I've ne'er used the other sort of protection biner aside from the screw gate, thus i do not have a lot of to check to in this department. however compared to alternative screw gate biners i might say that this one sticks the smallest amount. I conjointly like that it's sufficiently big on behalf of meto repel down a double rope and still have some space. All in all, an excellent obtain and that i can suggest this to friends once requesting a decent belay biner.
The largest belay and rappel locker Black Diamond offers, the RockLock comes equipped with a keylock nose, a slightly curved spine to maximize gate opening and a square hinge end to hold the loop securely in place.
