T.P.E. (Thermo-Plastic Elastomer) Corner buffers can be fitted to new or existing trolleys with square corners. They stop much of the damage to walls, door jambs, etc. They are fitted by four pan head self tappers, which are recessed down inside each arm of the buffer (No. 10x1" or similar). Being made from T.P.E. they are very resistant to abrasion, chemicals, etc. The end profile is matched to the 'D' section rubber strip.
