Rated 5 out of 5 by from Best value waterproof box I always use these robust BG boxes for external electrical connections and never had one fail or leak yet. The substantial rubber gasket is flat (does not sit in a groove) which is why the rating is IP55 and not IP65 but this does not appear to be a problem for most applications, providing the lid screws are tight. I find it better to use the screw to cut a thread in the box before putting the lid on as this can be awkward in situ and they can be very tight.

Rated 5 out of 5 by from Does the job! Needed this as a temporary solution to cover an external plug whilst we have some work done. Easy installation and decent quality.

Do these boxes come with any relevant size grommets or are they a separate order?

Asked by: NotJuliantheFiddler
Hi NotJuliantheFiddler, As different gaskets or grommets are used depending on whether you are using conduit, steel-wire armoured cable or flex we have not included any, so you will need to get the appropriate item separately.

Double socket

Would a double socket and back box fit in this enclosure?
Asked by: Hp57
Hi Hp57, Double socket faceplates tend to be around 146 x 86mm or slightly larger, so would be a little too large to fit inside this box unfortunately.

How to remove the cut-outs?

The instructions say to use a 20mm "cutter" to remove the cable entries. What would this be? Can I use a flat wood drill bit? Or do they come out cleanly if bashed with a blunt screwdriver?!
Asked by: DrillerVanilla
Hi, thank you for your product enquiry. A cutter, or hole cutter, is a narrow drill bit for pilot/centring with a larger circular blade at the diameter of the hole which will be cut. The material of the box can be cut with a sharp blade if you don't have a cutter, a wood bit may work but would likely leave the edges a little rough (as the material doesn't behave exactly the same as wood does).

Lid screw size?

What size screws do I need to order to replace the screws for this enclosure? One of mine sheared when I was screwing the lid on so I need to buy some. I can't return the box as it's been drilled and fitted to the wall. Thanks.
Asked by: Burgs
Hi, thank you for your product enquiry. The screws used in these enclosure lids are 3mm diameter, 15mm long (with the end 6.5mm threaded) and have a 6mm diameter 2mm deep head on top of the 15mm shaft.
