Black Diamond Rocklock Screwgate Carabiner



Love 'em
I got a set of these 'biners for christmas, and I love 'em. They're so easy to unscrew when clipping in or out. Let's just say I wouldn't trust my safety with anything less.


I have no complaints with this...
It simply works. It is easy to screw and unscrew. I use this with an ATC-XP and both work well together. It is large so it's easy to slip into the harness and everything.


Worth the Price!
This is a nice set up. The locking biner is nice and sturdy. The ATC-XP is a good belay device but tricking when using thicker ropes.


does the job
Nothing fancy, easy to use, safe and gets the job done. I never second guess it and never had problems with it loosening... bomber goodness. Everyone needs a locking carabiner..so get it!


great screwlock
Great locker for setting up anchors: stays locked (as much as can be expected), clips easily and is plenty big to accommodate other ‘biners or haul system.
