In some cases, the box is mounted on the wall surface, serving to shield the wiring and components from exposure to dust and other potential contaminants.

The pattress box is a simple device that looks much like any type of box. Equipped with a bottom and four sides, the container fits neatly against what is known as a pattress plate. When installed correctly, the box is more or less sealed, providing a reasonable level of protection to the contents.

In terms of construction, a pattress may be composed of a durable plastic or some type of metal. In residential situations that normally call for the box to be within the wall, it is not unusual for plastic containers to be utilised. Metal containers are often used in commercial or manufacturing settings where it is deemed a good idea to have access to the electrical wiring without the need to extract it from the interior area of a wall.

The pattress is known by a number of other names. When the wall is composed of plasterboard or some type of timber construction rather than brick or cement blocks, it may be referred to as a plasterboard box. While the name may change, the essential function of the pattress remains the same.
