This wall-mounted storage rack is custom designed and 3D printed specifically to hold Hornady Lock-N-Load Headspace Comparator tools. It features 7 spots for bushings, as well as spaces for the body and anvil. Additionally, there's a designated spot for storing the 1/16" hex bit in the included tool holder. The rack is 2 1/2" wide by 4" tall and can be attached to the wall with 2 countersunk holes that fit common #8 wood, machine, or drywall screws. To install the hex bit, insert the small end into a 1/4" socket and gently press it into the plastic handle with a vise or similar tool. It's recommended to use a high-quality 1/16" hex bit, such as those made by Dewalt, as cheaper hex bits may not fit properly and could slip in the set screws. The package includes the wall-mounted holder and hex bit holder, but no hex bit or Hornady tools are included.
