IMP Brass Nut Set 2-4

These are soldered directly on to wires, allowing a thicker wire to be used and increasing the strength of the IMP. The swage on the wire is colour coded for quick size selection, and allows one side of the wire to slide, letting the IMP self equalize when loaded and increasing placement security.IMP's are invaluable for those pushing into harder grades and need to take advantage of all protection options. By fusing the bone tendons into the head material, the manufacturer was able to increase the surface area of the side walls of the bone head, and thus increase the contact area with the crack. Such a solution allows the load to be distributed more evenly, which is especially useful in loosely bound rocks. It also made it possible to use thicker steel wire, increasing the strength of the entire bone. The DMM brand was built by trad climbers - so they realized how annoying the situation can be when we are a few meters above the last passage and in the only crack in our reach the bone we left a few pins below sits perfectly. That's why there are large, even tens of percent, compatibility between the different sizes in terms of range. Together with the aforementioned ergonomic shape, this makes climbing on your own much more pleasant. DMM, in an effort to speed up finding the right size bone, decided to subject the bone tendons to an anodization process. In addition to the visual aspect, this process also affects durability. The surface of the aluminum used in the production gains anti-corrosion and mechanical protection, which will be especially appreciated, for example, when climbing on cliffs. What's more, the colors are compatible with DMM mechanics, among other things, and the manufacturer also offers hardware carabiners anodized in IMP colors - quickly setting the right size in difficulty has never been so easy.
