SMC NFPA Aluminum Locking D Carabiner – 27 kN, Made in USA

The SMC NFPA Aluminum Locking D Carabiner is a lightweight, high-strength connector designed for technical climbing, mountaineering, rescue operations, and industrial applications. Its modified D-shaped aluminum frame provides a wide gate opening and an efficient strength-to-weight ratio. The locking sleeve engages directly on the gate to help reduce jamming and unwanted movement.

Featuring stainless steel internal components and a lightweight aluminum construction, this carabiner is UL certified to NFPA 1983 Technical Use (T) requirements. SMC visually and physically inspects its carabiners, and each NFPA product includes the required certification markings and user information.
