Attache Locking Carabiner
The Attache is a smaller screwgate locking carabiner that is designed to be used in anchor systems, belay stances and tie-ins.
This biner uses Petzl's patented Keylock gate closer that prevents the biner from haning up on ropes or webbing on protection and anchors.
There is also a red security ring in the locking mechanism that allows you to glance at the biner and confirm that the screwgate is closed.
The pear shape of the biner makes it easy to use with an Italian (Munter) hitch on a single rope.
