DMM Revolver Screwgate

2 reviews   |  

The DMM Revolver Screwgate is a unique screwlock climbing carabiner, designed to reduce friction on the rope.

Featuring a uniquely designed pulley wheel that reduces friction and allows the rope to run efficiently through the carabiner, the screwgate version is an ideal biner for extra security use in hauling or rescue systems.  

The Revolver uses advanced I-Beam technology which is designed to crucially allow the body of the biner to deal with the stresses involved in placing a pulley into a carabiner, whilst remaining light enough for general use. It has also been anodised for protection against the elements especially coastal and mountain environments.


  • Integrated pulley wheel for reducing friction, rope drag on complex pitches, and rope wear when used as an anchor for top roping. The pulley wheel is functional with loads up to 11kN.
  • Keylock nose to eliminate snagging
  • I-beam construction for optimal strength to weight ratio 


  • Gate Clearance mm: 16

    It has helped reduce the friction in my standard rope ascending pulley set up.

    Possibly the best carabiner for top roping or lowering possible? Save your rope, it costs a lot more than one of these.
