Preformed cavitray for use over standard meter boxes (gas or electricity).


The Type M cavitray provides horizontal protection against damp penetration where a cavity wall accommodates an electricity or gas meter consumer supply control unit (meter box). The standard length tray suits standard meter boxes and provides sufficient overhang to each side. Water discharge off the ends of the Type M is prevented by integral stop ends. The base of the Type M suits standard thickness exterior skins of brickwork, blockwork etc., whilst the cavity upstand of the Type M automatically adjusts to suit most cavity widths from 50mm up to 160mm.
