The Petzl Attache screw lock is an ultralight pear-shaped screw-lock carabiner with a round-stock basket to ensure ropes move smoothly across the surface. The design combines a H-shaped frame — which reduces the overall weight while retaining strength — with a round stock at the point where ropes run across the surface of the carabiner. This allows smooth rope movement, better abrasion resistance, a longer lifespan, and prevents sharp edges forming. The keylock gate helps prevent the carabiner from snagging during use, while the gate features a visual indicator that makes it obvious when it hasn’t been securely shut. Suitable for a range of uses, including as a primary attachment for a canyoning descender, belaying with Munter hitch, and a range of other rigging and rescue settings. Note: The Attache Bar accessory (sold separately) can be added to the carabiner to prevent accidental cross-loading.
