Woodpeckers Super Track, 48 Inch, 7-in-1 Aluminum T-Track, USA Made, Universal Multi T Track for Woodworking, Fixtures, Hex Nuts, Hex Bolts - SPT-48

Woodpeckers Super Track are great accessories for jig and fixtures because they are a heavy-duty, general purpose T-track for a variety of woodworking applications. These tracks fit any standard 1/4-inch fastener such as hex nuts, hex head bolts and 7/16-inch wide oval nuts. In fact it's these very fasteners that make Super Track so easy to install. Simply drill holes in the work surface, drop in some 1/4-20 hex head bolts and slide in Super Track. Very simple, very easy. A big advantage bolting from the bottom has over screwing down from the top is resistance to pullout. Bolting from the bottom has dramatically greater resistance to pull to pull out. If you use knobs to lock the hex head bolts instead of hex can easily adjust the position of Super Track. Super Track can be used horizontally or vertically, on top of or embedded in a jig, fixture or work bench.
