Rated 3 out of 5 by from Cheap for a reason! On the face of things it looks like a great buy however..... Please be aware that the centre screw must NOT be overtightened, and by that I mean what most people would consider to be tight. I tightened the screw to prevent the sliding covers from moving and the centre section broke away from the main body and had to be reglued in place. I am not a ham fisted novice by any means so BE WARNED! On the plus side the grub screws are well threaded and as are the grub screw inserts. Had I not had the issue with the centre section I would have awarded this item 5 Stars which is a shame as it's clearly a design fault.

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.

Always wondered what the numbers on the top mean?

Asked by: HKun
The numbering on top allows you to twist the cover to align the entry/exit holes and have two, three or four open to take cables with the rest shut off. This allows it to comply with the 2 of the IP20 safety rating which is to prevent fingers or similar being poked inside when fitted.

Are these suitable for outside use

Asked by: willywonga
Hello willywonga, This only has an IP20 rating so would not be suitable for use externally. Thank you for using Q&A SW
