Rock-N-Rescue SMC NFPA Large Heat-Treated Steel Locking D Carabiner

SMC NFPA Large Heat-Treated Steel Locking D Carabiner

Heat-treated Large Steel Locking D was created to address the need for a very strong steel carabiner without adding unnecessary weight and size. Built to the same specifications as the standard SMC Large Locking Steel Carabiner and certified by Underwriters Laboratories to meet NFPA “G” General Use standards but with an additional step of heat-treatment in order to provide an incredible 30% greater strength.
