If you are looking to buy an American-made Stainless Steel Carabiner then you need look no further. SMC-s Stainless Steel Large Locking D Carabiner is manufactured in the same size and shape as our best selling Large Steel Carabiner. When the working environment results in exposure to corrosive elements, and a larger gate opening and higher breaking strength are necessary, the SMC Large Stainless Steel Locking D is the correct choice.

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.

This is one of SMC-s best selling steel carabiners. The Large Steel Locking D was developed especially for the needs of the fire and rescue communities with a large gate opening that easily fits over litter rails. The NFPA21001 & NFPA21007 are the models that are stamped with the requisite UL Certification.
