2L offers a replaceable aluminum top plate for the modular Vac-Vise vacuum chuck systems. The precision ground replaceable top plate works in conjunction with the vac-vise modular vacuum chucks. It covers the surface of the vacuum chuck to allow drilling through and milling around the periphery of workpieces without damaging the surface of the vacuum chuck. The hole pattern of the top plate is identical to the vacuum chuck for quick setup and consistent workpiece placement.

The aluminum top plate fastens securely to the vacuum chuck with the included brass screws which can be machined without causing damage to the standard cutting tools being used to machine the workpiece.
