SMC Large Steel Locking Carabiner

A super durable industrial access & rescue connector

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, ladder rungs etc.

The components used in this carabiner are meticulously hand-finished prior to final assembly resulting in the smooth, free gate action that is the hallmark of all SMC carabiners.  The sleeve locks on the gate rather than the body of the carabiner, eliminating the problem of the sleeve binding on the frame after the carabiner has been loaded.

Other features include:
  • the carabiner utilizes stainless steel gates and locking sleeves for smooth action, greater strength, and optimal reliability.
  • each carabiner is 100% hand-inspected for gate action and other functional characteristics before leaving the SMC factory.
  • perfect for heavy duty rope access and industrial rescue applications.

Please note that adequate training and judgment are needed to reduce the risks inherent in the use of this equipment. It is the responsibility of the purchaser to ensure that the user is adequately and competently trained in the use of this product. We strongly advise that you do not use any carabiner without first undertaking appropriate training.
