DMM Halfnut 10 Colour:Silver The pulley reduces rope frictionHalfnuts excel in shallow placements, pin scars and situations where every gram counts. If they look familiar its because they have the same tapered faces and side profile as DMMs tried and tested Wallnuts. The reduced width makes them ideal for shallow cracks, pin scars, and situations where every gram counts. The combined weight of the 1 11 Halfnut sets are 42% lighter than the equivalent Wallnuts and they are similarly colour coded.
