Lightweight nuts that increase protection options. 
Halfnuts excel in shallow placements, peg scars and in situations where every gram counts.
  - The set from 1 - 7 is 38% lighter than the equivalent Wallnut 1-7 set.
 
  -  Reduced width gives more stability in shallow placements.
 
  -  Unique shape creates additional placement possibilities.
 
  -  Same reliable profile as classic DMM Wallnuts.
 
  -  To gain the weight saving you should replace a regular nut on your rack with a half nut. If you just add the half nuts to your rack it will be heavier!
