SMC Aluminum Locking D NFPA



The SMC Aluminum Locking D Carabiner NFPA sets the standard in climbing, mountaineering, and rescue scenarios. These carabiners are extremely lightweight while still maintaining high strength and a versatile large gate opening. The SMC Aluminum Locking D Carabiner NFPA’s locking sleeve engages the gate rather than the frame which prevents jamming and accidents.
