FAQs

What is a pattress box used for?

A pattress box, also known as a surface mounting box, is used to house electrical accessories like sockets or switches when they are installed on the surface of a wall, rather than recessed into it.

Can this box be used with metal accessories?

This is a plastic pattress box. While you can fit metal accessories into it, ensure that any metal faceplates are correctly earthed as per electrical regulations.

What is the depth of this box?

The depth of this BG pattress box is 30mm.

Do I need to chase into the wall to install this?

No, the primary purpose of this surface mounting box is to avoid chasing into the wall. It is designed for external installation on the wall surface.

What size accessories can I fit in this box?

This is a 2-gang box, designed to fit standard UK double-sized electrical accessories, such as twin sockets or double light switches.

Is this suitable for outdoor use?

This product is typically designed for indoor use. For outdoor installations, an appropriate IP-rated weatherproof box would be required.

How do I clean the box?

Clean the plastic pattress box with a soft, damp cloth. Avoid using abrasive cleaners or solvents.

Troubleshooting

Pattress box is not flush with the wall

Ensure the wall surface is flat and smooth. If the wall is uneven, consider using a flexible gasket or filler around the box edges.

Accessory does not fit securely

Check that you are using a standard UK double accessory. Ensure the accessory's dimensions are compatible with the 30mm depth. Verify screws are tightened correctly.

Difficulty routing cables

Utilize the pre-made knockouts or carefully create openings for cable entry. Ensure cables are not pinched or damaged during installation.

Box feels loose after mounting

Re-check that appropriate wall plugs and screws are used for the wall type. Ensure all fixing points are securely tightened.
