Boxes are also available with a Mirror polished flap and handle, or total Mirror finish.

Standard finish - no trim

Note: All stainless steel & brass lids and frames are made to suit your floor. Please specify lid recess when ordering, also if you want a brass or stainless steel finish. Frames come as standard without a trim flange. They can be supplied on request.

Flaps and trim frames can be supplied in a mirror polished finish.

As supplied with trim

We hold a large number of standard bases in stock, with a lead time of a few days to be ready for wiring. Please note that the tops are made to order and are typically available in a few weeks.

As standard these boxes are designed to lay within a base box fitted to the sub floor. Note that the base box of a standard install box is 10mm larger than the frame size stated above. Therefore, if the floor finish is already down we suggest a RETRO type base box that fits within the cut out size required for the stainless or brass trim frame. Please tell the sales team if your finished floor is already fitted. A minimum of 75mm is required from the top of the finished floor to the bottom of the sub floor. This method can also be used for replacing existing floor boxes without re-wiring. All base boxes are suitable for installation into cavity or screed floors.

A small selection of available plates is shown below. For others, including non-standard, 5amp sockets, and RCD protected sockets please click here . Also available is a CAT6 compatible angled date plate, for use with boxes of 85mm or deeper, to allow 50mm bend radius.

Standard plates are made from grey plastisol with white socket interiors. Stainless steel or brass plates, and black or red socket interiors are also available.

To increase available plug top space, either the plate can be dished (affecting single plate only), or the galvanised inner frame can be increased in height (affecting all plates)

* Note our socket plates are off centre, so that when multiple socket plates are used they should be installed facing each other so that the plug tops are staggered when in use.

** Note that we are aware of a problem of some high-powered radio systems interfering with RCD sockets.


Any installations using such systems should contact the Contactum Techical department on 020 8208 7414
