DMM™ Micro Wallnuts

When the cracks are too small for Wallnut 1s it's time to get out the "Micro Wallnuts". These little beauties work well in narrow cracks because they spread the load through a relatively large surface area. The Micro Wallnuts are designed to fit in placements smaller than a wallnut 1, these straight sided nuts are suited to the more 'standard' placements and range from 4 mm to 12.6 mm. Ultra lightweight, the nuts are machined so that the wire can be recessed onto a full radius inside the nut combined with a large surface area to dissipate the load. This makes them stronger and protects the wire; it also means the nuts will fit into tighter placements for routes where suspect rock may be encountered.
