Proper support of granite surface plates is essential to maintain the specified accuracies. All granite plates are finish lapped on three-point support pads and these heavy-duty stands are custom designed to provide the proper three-point support required for each plate.
Stands are constructed for exceptional strength. Legs include leveling screws and leg length is designed to provide a 36" working height to the top of the surface plate unless otherwise specified. Standard finish is machine tool gray.
