Description
This locking asymmetric spring hook adds a knurled screw nut that threads over the gate, so the hook cannot open by accident. The working load limit ranges from 250 lb on the 1/4" size to 700 lb on the largest.
Choose it when a hook will be left in place, for example on a boat cover tie-down or a hanging load.
Features
- Eyelet end for attaching to rope or webbing
