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 of the SMC Large Steel Locking D Carabiner include:-

  • The carabiner utilises 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.
  • The carabiner is perfect for heavy duty rope access and industrial rescue applications. For something smaller and lighter, have a look at the SMC Aluminium Locking D.
  • The Large Steel Locking D is made in the USA.
