FAQs

Can these be used in concrete walls?

No, these are specifically designed for plasterboard or stud walls using a clamping mechanism.

What is the maximum wall thickness these can handle?

These boxes are designed for walls between 3mm and 18mm thick.

Do these come with screws for the face plates?

The back box typically includes the mounting screws for the side clips; face plate screws are usually provided with the switch or socket itself.

Can I fit two of these side-by-side for a double socket?

These are individual single-gang boxes. If you need a double socket, you should purchase a dedicated double-gang back box.

How do I wire the cables into the box?

The rear of the box features cable entry points where you can feed your electrical cables through before securing the unit to the wall.

Troubleshooting

The box feels loose in the wall.

Check that the side clips have fully engaged with the rear of the plasterboard and tighten the mounting screws firmly.

Face plate will not sit flush to the wall.

Ensure the drywall cut-out is not too large and that no debris is trapped between the box flange and the wall surface.

Cannot fit the box into the wall cavity.

Verify that your wall cavity has at least 47mm of clear depth and that no wall studs or insulation are obstructing the space.

Pros and Cons

Pros

  • Simple, tool-less clamping mechanism for easy installation
  • Deep 47mm profile accommodates bulky wiring and modular components
  • Compatible with a wide range of standard UK face plates
  • Designed specifically for secure mounting in drywall and plasterboard

Cons

  • Requires sufficient wall depth clearance of at least 47mm
  • Not intended for masonry or concrete wall installations
  • Limited to single-gang configurations

Setup, Compatibility & Care

Installation requires a sharp drywall saw or a 75mm hole saw. Ensure you have mapped your electrical circuits and turned off the power before cutting into any wall surface.

Compatibility:

These units are compatible with all standard UK face plates including single-gang light switches, power sockets, dimmer modules, and Cat6 Ethernet face plates.

Care Instructions:

  • Ensure the plasterboard edge is clean before inserting to allow the clips to grip correctly.
  • Avoid overtightening the screws, as this could potentially damage the plasterboard if the wall material is fragile or thin.
  • If removing the unit, gently loosen the screws to retract the clips before pulling the box out to prevent damaging the drywall opening.
