DMM Wallnuts Set Assorted 1 - 11. Larger Wallnuts feature hollow construction to reduce weight. Wallnuts can be placed in two different orientations allowing a single nut to cover a range of cracks. They are tapered across both their face and sides helping them sit better in cracks that are rarely parallel sided. Grooved faces reduce weight help the nut seat better in cracks improve security in shallow placements and resist lifting out when a leader moves past them. Wallnuts are mounted on wires that are stiff enough to allow overhead placements while flexible enough to reduce the chance of lifting out. They are colour coded to correspond with the rest of our protection range and to give quick and easy selection of the correct size from your harness. Wallnuts are the basis on which to build a comprehensive climbing rack. Complemented by other more specialised pieces of protection they are guaranteed to be the most regularly used piece of protection on your harness.
