They are fitted over an existing electrical box, extending its body so that the front can be flush mounted with the surface. 1 gang extension boxes are suitable for use with flush-mounted accessories and come complete with knockouts for improved ease of wiring. The 1 gang extension boxes we offer are manufactured from galvanised steel making them highly durable and reliable. Most importantly, a 1 gang extension box provides greater cabling and wiring space for your installation requirements.
