⚡ At a Glance
  • Wiring Space: 118.5mm internal width and 20mm depth create ample room for connectors, cable bends and smart modules while keeping a low-profile extension.
  • Best for: Installers and renovators fitting standard UK 2-gang sockets on tiled, panelled or splashback surfaces.
  • Not ideal for: Installations that require more than 20mm of extension or bespoke deep enclosures.

Provides a 20mm extension with mounting points on both sides for secure fitting. The internal width of 118.5mm helps avoid cramped wiring behind faceplates.


Neat finish on tiles and splashbacks – with a 20mm extension and 5mm corner rounding

A 20mm projection lifts the back box surface away from tiles and panels, while 5mm corner rounding reduces the risk of tile edge contact and visible chipping. The spacer matches common faceplate profiles for a flush appearance.

Achieves a tidy, consistent edge between tiles and socket faceplates, removing gaps and awkward cutbacks during renovation work.

Easier access for wiring – thanks to an 118.5mm internal width

A wider internal cavity increases usable space behind the socket, allowing room for connectors, cable loops and small smart modules that need extra clearance. The design keeps cables from being pinched against the wall surface.

Saves time during installation and reduces the chance of damaged or strained cables in crowded back boxes.

Secure, repeatable installs – with mounting points on both sides

Pre-formed mounting points accept standard fixings to anchor the spacer firmly to the wall covering, delivering a stable 20mm offset without extra brackets. Symmetrical mounts make alignment straightforward.

Installs quickly and holds faceplates steady, useful for professional installers and DIYers working across multiple rooms.
