The wire comb allows perfect bundling of up to 37 wires from switch panels and other accesories.  Simply insert each wire in the desired order and slide and place a ziptie at whatever spacing you want.  This will stop wires from crossing over each other resulting in the cleanest looking bundle possible; it also allows for more consistent twisting of the bundle if a twisted bundle is needed.
