The Granite Surface Plates that we offer are marked on the bottom of the plate to coincide with the supports on the top of the stand. When aligned with each other they uphold the accuracy of the plate. These Granite Surface Plate Stands are manufactured to support the weight of the surface plate plus 50 pounds per square foot load.
