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 length of wood (not supplied) needs to be secured between each pair, forming two supports. The bracket has a downward facing socket into which a length of wood may be ½tted 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.
