Modular Riser Plates, 4 in. x 4 in. x 0.25 in., 1/4-20 Thread

The MRP4-0.25 Modular Riser Plate raises the surface of an optical table, allowing components to be securely mounted at a fixed 0.25 inch height. 4 x 4 inch Modular Riser Plates can be stacked to achieve any height in 0.125 inch (3.175 mm) increments. Ample 1/4-20 threaded holes on the top surface are available to mount components to riser plates. These riser plates can be directly bolted to a table surface or mounted off the hole pattern using base clamps. 0.5 and 1.0 inch (12.7 and 25.4 mm) high versions have a groove around the base for the base clamps.
