Flush Metal Boxes

Some of the most popular and useful back boxes are the Flush Metal Boxes, and at Sparks we offer a wide variety of such metal back boxes.

These differ from the surface-mounting boxes and from the dry-lining boxes, and they are in particular for the wall-mounting switches, sockets, and other wiring accessories.

The flush mounted metal boxes at Sparks can be single or double back boxes, and their depths can be 16mm, 25mm, 35mm, or 47mm.

Select the desired flush metal box from the list below.

If there is a flush metal box that you require or wish to replace but do not find in the list below, do not hesitate to email us or contact us, and we will advise.

If you are local to us in London, you can visit our lighting showroom in N19 5SE to see them for yourself, for we hold large stocks of the flush mounting boxes, whether single or double, and whether 16mm, 25mm, 35mm, or 47mm.
