DMM Sentinel Carabiner

The DMM Sentinel is an aluminium HMS (pear‑shaped) locking carabiner designed for belaying and general rope work. It was produced in locking variants, commonly as Screwgate, Locksafe or Quicklock.

Key benefits

• HMS / pear‑shape accommodates belay knots and provides stable orientation on belay devices and anchors.
• Locking gate — available as Screwgate, Locksafe or Quicklock variants for added operational security.
• Wide gate opening simplifies clipping and handling with various knots and connectors.
• I‑beam strength construction reduces weight while maintaining load capacity.
• Engineered primarily for belay and ropework rather than specialised via‑ferrata use.

Typical use includes belaying, anchoring and routine ropework in climbing and rescue contexts. The model has been discontinued by the manufacturer and is listed as unavailable.
