IMP's (Immaculate Marginal Protection) are 'brass' micro wires that have a regular taper. They are the ideal basis for any experienced leader's rack of micro gear.
When developing these nuts DMM gradually honed in on an alloy and a hardness that allowed both 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. Colour coding means you select the right nut first time, every time.
- Heads machined from new copper alloy to control hardness
- Every unit proof loaded to 75% of its strength
- One wire runs free so head always loaded optimally when it holds a fall
- Colour coded
