Hose holder pieces. These are for if you upgrade hose sizes, want more pieces, or want our laser mount
The hose holder is for the piece that attaches to the extension pieces and holds the hose
Extension pieces make the holder taller. The X mount will screw directly in and the Z motor will attach to the top of the Z motor piece.
Bracket refers to the piece that attaches to the spindle or Makita mount. Comes with the same type of bracket as the rest of our bracket system. The bracket will attach to the mount then the hose holder will slide onto the bracket. 
Z motor laser mount. You can mount the piece to the z motor and have a place to store your laser when not in use. To use this mount with your laser you will need to purchase our laser mount.
