DMM Big Wall & Protection IMP Brass - 3 Strength 5kN A1723.
When you're high on the wall and the cracks get small, the DMM IMP brass nut set lets you confidently take advantage of the smallest and most marginal placements with 5 sizes of tiny yet mighty IMPs.
Named DMM's Brass Immaculate Marginal Protection Nut Set, the I. M. P. pro boasts full strength ratings at low weights. When you inevitably have to make a desperate clip, let your shakes subside with the knowledge that these color-coded wires are easily identifiable for quick placement. Slightly concaved faces make these pro pieces extra secure and ready to catch, while a double reverse taper resists rotating or wiggling.
