Universal Base, Freely Rotating Disk, Eccentric Clearance Slot

The BUP-2 Universal Base incorporates a patented mounting device that gives unprecedented positioning flexibility. A freely rotating disk, inset into each base, has an eccentric clearance slot to accommodate a 1/4-20 or M6 tie-down bolt. This single bolt firmly clamps the assembly to your table surface. The slot permits 0.707 in. of translation - at least half the diagonal distance between holes in Newport’s English and metric tables, breadboards and mounting components like lab jacks and stages. Thus it is always possible to find a mounting hole through the clearance slot by rotating the trapped disc; the bases can be freely positioned anywhere, at any orientation, on your table surface.
