How to pierce a junction box??

[shocksl]

I bought this junction box from screwfix. I need it to put my cctv camera connections in there.

https://www.screwfix.com/p/vimark-4-entry-square-junction-box-with-knockouts-82mm-x-52mm-x-82mm/999vt

Outside near the camera. So a camera cable will come into it and one cable that is for power and DVR which goes to the room its in. So I need 2 holes .

Do I pull them things out that are in rhe holes? Or drill in them? Do I just feed the wire in them. Or do I need a special gromit etc ? I am not using any conduit etc. Also shall I feed the cables in the horizontal holes to avoid raining getting in from the topnotch the box?

Thanks for any help.

You would be better off using something like this and using suitable compression glands for the cable.

The junction box you have is not really suitable if open to the weather.

And yes cable entry from below if possible.

The holes in the first box, if you take the plastic gromits out, are slightly bigger than the standard 20mm.
The gromits can be slit with a knife, or drilled out…. Or not used at all and the holes filled with sealant.

It’s only for CCTV, so not mains voltage, but water ingress can still be a problem… as can spiders and such setting up home inside the box.
CCTV also suggests the cables you are running will have fixed plugs on the end… compression glands may not close up enough to seal around such small cable size.

Gromit and grommet.

They do various types of split glands.

If the seals in this box are of the thin, flexible type, then I know from experience that the unused ones will fail in time if exposed to sunlight.

Those boxes are total carp and will deteriorate when outside, but there again what do you expect for £1.50.

Regrettably, you get what you pay for… so first link, the cheaper one, is only IP54…. So not completely weatherproof… but maybe ok under a soffit, or somewhere sheltered.

There is a customers image on the page showing it being used with CCTV cabling.


the other issue is the lid simply clips on. If it’s not screwed flush to the wall, and the plastic bends out of shape, the lid won’t stay on.
