A generously-sized biner for belaying and rappels. No corners to trap the rope, so you get smooth action and it dissipates heat on long raps.
- Curved spine for clearance.
- 25mm gate opening and snag-free nose for smooth clipping.
- 111 x 76mm.
Auto-locking biners use a spring mechanism to close. Screwgate have a collar that you screw open or closed.
