These are suitable where a stronger more permanent raise or where greater heights are required, than can be achieved with most raisers. Four white steel brackets screw to the sides of the bed or chair. A lenght of wood (not supplied) needs to be secured between each pair, forming two supports. The bracket has a downward facing socket into which a lenght of wood may be fitted to give a leg of required height. Without a wooden leg insert, the raiser gives a rise of 150mm (6"). Weight 6.9kg. Supplied as a set of four. Max. total load: 50st / 318kg.
