Made with a wide opening for use with rope, the Petzl Triangular Screw Link is a compact, lightweight alternative to carabiners for semi-permanent attachments.
Features
Stands up to force in any direction--including three-way loading when screwed closed
Constructed of galvanized steel for a breaking strength of 9,900 pounds
Triangular shape creates the room needed for cavers' seat harness and all the gear which needs to be clipped into a central point
Links are marked with a Normal Working Load, (NWL), which is about 1/5 of their strength
