Main Features of the DMM IMP

  • Brass micro nuts on wire
  • Machined from silicon bronze
  • Silver soldered for strength
  • Aluminium swage aids even loading
  • Colour coded for easy recognition
  • 5 sizes

IMP's (Immaculate Marginal Protection) are straight sided 'brass' micro wires that have a regular taper. They are an essential addition to any experienced leader's rack.

The heads are machined from a silicon bronze that has very specific properties and a carefully controlled hardness which allows both a good bite and also a good resistance to shear forces - this way the nuts lock into the rock well and also resist being pulled through the placement. The heads are then silver soldered onto stainless steel wire and every unit is proof loaded to 75% of its rated strength.

These wires benefit from a colour coded alloy swage that is only dinked on one side i.e. one wire runs free so that the head is always loaded optimally when it holds a fall. The colour coded swage helps with selecting the right size first time.
