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.
The SMC Swivel is a piece of high performance gear with silky smooth action and a beautiful finish and feel – its exceptional quality is immediately apparent once you pick it up…we’ve seen that most people won’t put it down once they have it in their hands!
The TR Pulley is strong, reliable compact, and lightweight. It is reasonably priced but doesn’t sacrifice efficiency. Great performance for its size and cost. The TR Pulley has a true Oilite Bearing on a zinc coated axle for reliable performance.
