Gone are the clunky, heavy beasts of old - DMM Torque Nuts are a light and sophisticated answer to big crack protection.__ The Torque Nut shape fits well in normal crack placements, and they have the extra advantage of working extremely well when placed in a camming position - experiment with this at the bottom of the crag!__ They have a double sling, so you can clip them to your harness, doubled up and neat and they won't be clanking down by your knees. You then have the choice of a quick extension once the nut is placed. If you're close to the ground, keep it short to reduce fall potential. Further up the pitch, pull it into the extended position to reduce drag.__Large camming nuts Double dyneema sling 4 sizes covering a large range Anodised for ease of recognition and corrosion protection Torque Nut 1-4: total weight 374g
