It is designed to fit all Pinnacle shelving and urban series workbenches with a 540mm shelf depth or as standalone units due to its stackable design. It comes pre-assembled with a magnetic door catch, full length metal handle and a powder coated matte black finish. The door is adjustable to open from either the left or right side of the cabinet. For the best finish it is recommended to adjust the shelf height to the height of the cabinet so it fits flush between the two shelves. This secures the cabinet and reduces the risk of it sliding out. For standard shelving, leave 10 keyholes free between shelves and for heavy duty shelving and urban series workbenches, leave 8 keyholes free between shelves. Shelving units should always be secured to a wall to prevent them from tipping over.
