The TrackMaster™ from Milescraft is an innovation in clamping adaptability that works for all of your existing bench clamps. The TrackMaster™ is compatible with any brand or size of bench clamp that mounts with a 5/16in – 18 fastener. The TrackMaster™ comes with 4 different sizes of T-Bolt fasteners making it compatible with virtually every workshop track system on the market! Quickly convert any bench clamp from 1/4in T-tracks, to 13mm, 20mm, 30mm, or 35mm tracks. Multiple mounting fasteners are included that work with the T-Bolt you need. No matter what track you are using, the solid, heavy-duty base helps spread the clamping pressure evenly across your table top, reducing track tear out. The non-marring base shoe also prevents scratching and damage to your work table surface. Also included is a 3” BenchClamp™ so you can immediately get to work. The system works great on drill presses, fences, and bench tops for firm clamping while assembling projects. Up your track clamping game with the Milescraft TrackMaster™.
