Versatile, High Strength, Alloy Carabiner


The enduring design of the SMC Locking D has become the standard in rock climbing, mountaineering and rescue applications as well as in an ever increasing base of industrial applications. This is due to its high strength, light weight, wide gate opening and functional versatility.

Features of the SMC Aluminium Locking D include:-

  • The nut of the locking sleeve engages on the gate – not on the carabiner frame – this helps prevent jamming or vibrating loose.
  • The small offset D frame fits easily in the hand and aligns well with gear such as pulleys, Protraxions etc.
  • The narrow bar stock used to create the frame means the carabiner is compatible with all devices as well as Australian style bolt hangers.
  • It is ideal for mountain rescue & rope access use.
  • That it is made in the USA and individually inspected by the manufacturer.
So, What's Special About the SMC Locking D?

Yes, this carabiner has been around FOREVER, but doesn’t that just prove that if something is good, don’t mess with it. This is a simple, well designed tool that works. The price is good too which adds to the point score.
