Made from Polyurethane, these round leg buffers are used to prevent damage to corridor walls. The buffers are placed onto tubular legs just before the castors. When a trolley approaches a wall the buffers make contact first and freely revolve on the tubing, thus rolling the trolley along the wall so it causes no damage. In the case of 25mm square tubing the polyurethane buffers are supplied with a 38mm hole, together with a 'dress-cap' with a 25mm square inner and a 38mm round outer.
