Behind a wall-mounted TV there is usually a hole, a bundle of leads and a gap that collects dust. A brush plate and a flex outlet both tidy it, which is why people order the wrong one. They suit different cables, and they sit in different plate systems.

What each part does

A brush plate is a Euro module front plate with a brush insert. Cables pass through the bristles, which close around them and hide the gap. TEO stocks 30 of these brush cable entry plates, from £7.40, checked on 4 November 2026.

A flex outlet is a round exit for one cable. The BG Nexus flex outlet is a grid format unit built from a mounting frame, a faceplate and the outlet itself, and its listing says it suits cable up to 10mm outer diameter.

Which one does your cable need?

Count the cables and measure the thickest. That settles most orders.

Worked example: a wall-mounted TV

Say the TV needs an HDMI lead, an aerial lead and a power lead. That is three cables, and two different voltage types.

1. List every cable and sort mains from low voltage.
2. Send the HDMI and aerial leads through a brush plate.
3. Give the mains lead its own route, never the same opening.
4. Measure the outer diameter of any single cable going into a flex outlet. It must be 10mm or under.
5. Match the finish to the sockets and switches beside it.

Euro module or grid: check the system first

Brush plates are Euro module plates. BG's Euro module catalogue lists apertures of 25 x 50mm for one module, 50 x 50mm for two and 100 x 50mm for four. TEO's listings call the plates 2 gang and 4 gang, and do not state module size or fixing centres, so measure your cut-out before you order.

Flex outlets belong to the grid systems, BG Nexus and BG Evolve. The two do not swap. Our guide to Euro module switches explains how they differ.

Finishes, prices and what TEO stocks

The brush plates come in ten finishes: antique brass, black nickel, brushed steel satin, black chrome, matt black, matt blue, matt grey, polished copper, satin brass and polished chrome. Single 2 gang plates run from £7.40 to £9.82. Double 4 gang plates run from £12.00 to £13.09.

For a single cable, the BG Nexus flex outlets start at £12.00 and go up to eight gangs. The cheaper route is a flex outlet module for an existing grid plate, which starts at £3.51.

TEO builds these plates from a BG brush module and a faceplate, and the listing says BG does not offer them as a standard item. Keep your order reference if you need a match later.

Where brush plate and flex outlet installs go wrong

• Mains and low voltage in one opening. BG's catalogue says modules of those ratings must not share a front plate aperture, citing BS 7671.
• Wrong system. A grid flex outlet will not fit a Euro module box.
• Cable too thick. The Nexus flex outlet suits up to 10mm outer diameter.
• Guessing the module size. The listings do not state it, so measure.
• Mismatched finish. Evolve screwless, standard and TV plates are different families, so compare against what is on the wall.

Buyer's checklist

• Count the cables and sort mains from low voltage.
• Measure the thickest single cable against 10mm.
• Check whether your back box and switches are Euro module or grid.
• Measure the cut-out, since module size is not on the listing.
• Pick a finish that matches the nearest sockets.
