Pattress boxes (back boxes) house the wiring behind a switch or socket, in surface-mount and flush-mount formats and a range of depths. This collection covers metal and moulded boxes for single, double and grid plates.
Choose the box depth to suit the accessory and whether it's a flush or surface installation.
