With this mounting plate, you can use a regular Bessey auto-adjust toggle clamp in a T-slot, securing it at any point on the track. Two sets of mounting holes let you attach the toggle clamp in line with the T-slot track or perpendicular to it. The plate also has two holes for attaching the plate to a T-track miter-slot slider bar such as the Incra Miter Slider bars, so you can use your saw table as a surface for assembly work.
