Title: Cover for electrical accessory box during plastering
Inventor: BOULTON ROGER DAVID
IPC: H02G3/14
Filed: 1989-04-14
Abstract: A cover plate for covering an electrical accessory box of the type adapted to be set into a wall to be plastered, comprises a rectangular plate 11 having means 7 for securing the plate to the accessory box, the margins of the outer face of the plate having outwardly directed rib means 20 formed thereon. The rib means 20 are typically ribs which are square in section, and are conveniently approximately 1mm wide and 1mm deep. The provision of such ribs at the margins of the cover plate assists in locating the position of the plate after plastering. A further advantage is provided by the fact that when the cover plate is flexed inwards this causes the plaster to crack at the ribs, thus making it easier to remove plaster from the cover plate. The cover plate is preferably coloured so as to be easily distinguishable from plaster which will be spread over it in use. <IMAGE>
