The Rack It PRO Castor Set is specifically designed to fit both the Rack It PRO 2 Door Cabinet (I/N 0027426) and 4 Drawer Unit (I/N 0027425).

With Rack It PRO, design, organise and keep your workspace tidy – install Cabinets or Drawers below your workbench, fit Overhead Cabinets above your Peg Board and place Drawers and Cabinets on top of each other.
