Petzl Attache Screw Lock Carabiner

The Attache Screw-Lock Carabiner by Petzl is designed to be used primarily for belaying. With a pear shape, it has plenty of room for clipping into the entire harness (leg loops and upper belt), as well as a key lock system that provides a snag free interaction. If you aren't using it to belay it is a great biner for anchors as well, because since the nose has no indention, it is easy to get in and out of the bulk of webbing used in most belay systems. With the screw-lock feature, you can tell if you have locked the biner with its "red your dead" line that stands out when you look down. Safe and easy to use, this is the biner to get if you are looking for a locking, belay biner.
