Longspan Levelling Plate
 
Longspan Leveling Plates, also known as Shim Plates are designed to level your Longspan shelving unit during installation. They are cut perfectly to match the shape of the base plates and have pre-drilled holes making them very easy to use. Each base plate is about 1 mm thick and they can be stacked ontop of each other when you have a lot of levelling to do.
