You may want to verify the slot size. Unless someone recut them they should be a common size (1/2', 9/16' or 5/8'). Take flat file and run it down both sides of the slots to remove any burrs or mushrooming. Mount these versatile blocks to any flat surface for machine table-style T-slot clamping. They can also be used on a machine table to clamp parts at specific angles or add more total clamping points. Secure the block to your table using the slot for a 5/8' fixture key (not included) on the bottom of the block.
