Great rock and warm season biner

By Jeffrey Johnston Ranked #268 - Carabiners, Quickdraws, and Belay Devices December 23, 2010

I have the one of each of the screw lock and auto locks. Both are great biners and does quite well for belaying and master point of anchors. I really like the snag free keylock nose.My only gripe is the auto lock has frozen open on me while alpine, and ice climbing. Just a bit of moisture gets in the mechanism and the spring does not have the tension to overcome the friction, so its a three season biner. Use the screw gate for winter use
