Edelrid HMS Bulletproof Triple II

HMS carabiner with a triple-lock closure
Innovative HMS triple-lock carabiner made of aluminium with a steel insert at the apex of the carabiner. The steel insert helps reduce wear in the rope-bearing area and minimizes the formation of wear grooves. By combining aluminium and steel, the carabiner brings together relatively low weight with increased wear resistance in the particularly stressed rope-bearing area. This allows the carabiner to be used for top-rope climbing as a weight-saving alternative to full-steel carabiners.

Features
Keylock closure mechanism for a good handling when clipping and unclipping
H-profile construction for high material utilization at low weight.
Steel insert prevents premature wear from rope friction or bolt hangers
