Petzl OK Screw-Lock Carabiner

Petzl OK Screw-Lock is a lightweight oval aluminium carabiner designed to keep pulleys, rope clamps and progress-capture devices perfectly aligned. Its symmetrical oval shape centres gear in the load axis, making hauling systems smoother and helping rescue, rope access and technical rigging setups run reliably and efficiently.

The smooth interior and keylock nose prevent snagging on ropes, slings or anchors, while the H-shaped cross section saves weight and protects the markings from wear. The manual SCREW-LOCK system with a red visual indicator is ideal for harsh environments with mud or ice where auto-lockers can struggle, giving you deliberate, visible control over whether the carabiner is locked or open – exactly what you want when your connector is part of a critical system.
