Granite Flat-Surface Plates
Corrosion resistant and nonmagnetic, these smooth plates also resist warping and abrasion. The extremely tight flatness tolerances provide an accurate reference plane for layout and inspection work.
Plates with two ledges are used to hold fixtures and instruments with clamps.
Laboratory Grade AA plates are for precision quality control work.
Inspection Grade A plates are for general quality control work.
Toolroom Grade B plates are for checking work throughout a shop.
Also Available: Other plate sizes. Please order 2245A999 and specify grade, length, width, thickness, and with or without ledges.
