A sacrificial leg is a component used in a warehouse storage system that utilises pallet rack. Adjustable pallet racking has two prime components - frames and beams1. These are arranged to provide a number of storage locations that are in general serviced by forklift trucks for the picking and placing of palletised loads. The rack''s vertical frames are the source of its load bearing capacity and are vulnerable to damage by a forklift truck when manoeuvring. Most of the damage occurs in the first metre of the frame''s height.
