Brass Offsets are crucial for protecting small flared cracks, often fitting perfectly where nothing else will go. The brass used for the head of the nut is soft enough to bite into placements, but hard enough to resist deforming and pulling through. Wires are soldered directly into the nut head, allowing a thicker wire to be used and increasing overall strength. The color coded swage gives easy size selection and allows the Brass Offset to self equalize when loaded, making the most of marginal placements.

When the going turns tricky and the only cracks you can find are too narrow for conventional nuts, it’s time to pull out the micro wires. It’s always better to have something, however small, between you and the ground. IMP stands for Immaculate Marginal Protection – a neat little acronym, but one which fits perfectly. IMP runners can never be considered as ‘trainstoppers’, at least not in the same way that a well placed Wallnut might be. But they can give unexpected holding power in marginal placements, particularly if you cluster the placements and equalise them so that the load is spread evenly. We’ve given them a special aluminium swage which holds the wires parallel but allows one wire to slide. This means the nut is loaded more evenly on both sides. The swage is colour coded too, so you’ll always pick the right one. Obviously these are quite a specialist nut, but anybody pushing into the extreme grades should consider them as an essential addition to their rack.
