This is the Evoges EMB2G47, a 2 Gang 47mm Metal Back Box Galvanised Steel Flush Mount BS 4662 available at Sparks for the best price.

The 2 Gang 47mm Metal Back Box is a robust, recessed mounting enclosure designed to house and support a pair of standard UK electrical accessories — such as double sockets, light switches, USB outlets, dimmers or smart modules — in flush-mounted installations.With a generous 47mm internal depth, it offers extra wiring space compared with shallower back boxes, making it ideal for installations involving multiple cables, deeper modules or accessories that require more room behind the plate. 

Constructed from hot-dipped galvanised steel, this box delivers strong mechanical support and corrosion resistance — qualities that help ensure a long service life in domestic, commercial or light industrial environments. Multiple pre-formed cable knockouts allow for flexible cable entry from the back or sides, helping make on-site routing cleaner and quicker. 

Designed to meet BS 4662 standards, this metal back box supports compliant and safe wiring work during new installations, rewires or retrofits. Its flush box format enables accessories to sit neatly and securely within wall surfaces — contributing to a tidy, professional finish.
