SMC Aluminum Locking D Carabiner

Industry-standard aluminum carabiner

The enduring design of the SMC Locking D has become the standard in rock climbing, mountaineering and rescue applications as well as in an ever-increasing base of industrial applications due to its high strength, light weight, wide gate opening and functional versatility. The nut of the locking sleeve engages on the gate – not on the carabiner frame – this helps prevent jamming or vibrating loose. Through continuous inspection throughout production, careful attention to detail and precision craftsmanship, SMC consistently manufactures product at the highest levels of quality.
