The Sentinel is one of the lightest mini HMS locking carabiners and it is a really good multi-functional locking carabiner that works really well as a both as a small HMS and also, because of it's slightly offset shape, as a great rigging/multi-purpose screwgate. The slightly offset design increases strength and directs heavy loads into the spine, but uses gently curved top bar with a generous rope radius that allows it to work well with both single and double rope controllers. The Sentinel works really well with all DMM belay devices - the Bugette, the Bug and the V Twin and it fits snugly on most belay loops reducing the likelihood of cross-loading. The new Sentinel features a keylock nose so that it clips and unclips smoothly without snagging. It has a deep basket and good gate opening making it a fantastic and versatile rigging biner. It is fully anodised, has full strength barrels to resist push-in forces and conservative 3 sigma ratings. Specifications: Weight 54g. Strength (gate closed): 24 kN. Strength (gate open): 8kN. Strength (minor axis): 10kN. Gate opening: 20mm. Rope bearing surface width: 9.2mm.
