Pattress
A pattress is a plywood or timber board fixed within in a partition to which equipment can be secured, such as ceiling roses, power outlets, basins, wall cabinets and so on.
Confusingly, the term ‘pattress’ can also be used to refer to a container or box (correctly described as a pattress box) that is positioned behind power sockets, light switches and other electrical fittings, and contains wiring, switches and other circuitry. This may sometimes be secured to a timber or plywood pattress.
These boxes can also be referred to as a ‘wall box’ or 'installation box' or, when it is recessed into the wall, a ‘flush box’. If it is installed within timber or plasterboard walls, it can be referred to as a ‘cavity box’,‘plasterboard box’, or 'dry lining box'.
A pattress box can be designed to be either surface-mounted, or can be recessed into a wall or skirting board.
