Show Description

When the cracks won’t accommodate nuts or pins, hammer in one of these units. The malleable aluminum head will form to fit the structure of the rock.

  • Aluminum is lighter than copper, though less durable for reuse.
  • Note these are intended for extreme placement. Properly placed they can support body weight; they will not support a fall.
  • Four sizes: 1, 5 x 12mm; 2, 6 x 12mm; 3, 8 x 17mm; 4, 10 x 17mm.
