The Òliba Screw Lock is a symmetrical, oval-shaped aluminium carabiner designed to ensure a central and stable positioning of large-section devices such as pulleys, rope clamps or knots like the Italian hitch, clove hitch or mule knot. It is an essential tool for vertical work installations, rescue, descent, and is especially valued in caving, where its hexagonal sleeve is compatible with a 13 mm wrench, making unscrewing easier.
