Rated 5 out of 5 by from Wiring junction box I have used these for years. They are made of a sturdy plastic outer casing. It has 4 terminals within it which is useful if using it to wire in a light fitting with a switch.

Rated 1 out of 5 by from Bit unhappy! Just went to finish off a job this evening having purchased this terminal yesterday, opened it up and found it's centre fixing and two terminals in bits! Brilliant not! Hopefully this not common but it's very frustrating nonetheless.

Rated 4 out of 5 by from 4 Terminal junction box. Very quick and easy to apply to the wall to set up split junction between electrical doorbell and security light , Very fast to wire and finish in minutes. Very pleased with the outcome and tidiness of the system.

Rated 5 out of 5 by from Basic and functional. A great junction box for a variety of tasks. Not pretty or ornate, but you're not going to fit these somewhere obviously on show are you? I happily used dozens of these in the shed, loft, roof cavities etc.

Can this be used to replace a ceiling rose?

I want to install downlights in a room and was wondering if this junction box is suitable to be installed in the loft to replace the ceiling rose? Also, are the terminals marked (eg: L, N, E)?
Asked by: S1lrd3
hello S1lrd3, This will be fine for your needs but terminals are not marked. It does come with a diagram however for installation. Thank you for using Screwfix Q&A. A.K.C.

Will these 20A terminal rounds fit through a standard cut out for downlights in a ceiling

Asked by: Salfordlad
No. I think a standard cut out for down lights is 57mm diameter and these junction boxes have a diameter of 91mm.
