Granite Surface Plates provide a reference plane for work inspection and for work layout. Their high degree of flatness, overall quality and workmanship also make them ideal bases for mounting sophisticated mechanical, electronic and optical gaging systems. Ledges are for work clamping purposes only, there are two types: one is 2 lips, either direction rectangular; the other is 4 lips, rectangular.
The adjustable surface plate stands are manufactured from heavy duty angle and reinforced for rigidity. They are designed to support the plates and have levelling screws to allow the plates to set accurately.
