IMP Brass Nut
The DMM IMP Brass Nuts are invaluable for those pushing into harder grades and need to take advantage of all protection options. The brass alloy used in their construction means that the nuts lock into the rock incredibly well, whilst also resisting being pulled through the placement. 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.

Additionally they are racked on extendable dyneema allowing the nuts to be neatly stowed on your harness and then extended when placed, eliminating then need for extra quickdraws. Four sizes are available covering a very wide range of large cracks.

Where the Shadow would rest on a bolt, the metal has been reinforced to provide durability, and a clean nose reduces snagging when clipping and stripping routes. The gate has chamfered sides to make gripping it with the thumb easier, and the size makes for easier clipping in comparison to the much smaller lightweight carabiners.
DMM
Deadman
In winter, there are times when the only thing to lodge an anchor in is the snow itself. The DMM Deadman lets you make the most of this medium and improves on the classic ice axe belay by creating a larger surface area that increases resistance to the placement pulling through. Used in snow gullies and below cornice top outs, the Deadman creates protection out of nothing and provides security in the most insecure places.
