Can this be surface mounted for use with 20mm plastic conduit in a small workshop setting or does it have to be sunk into the wall? Thanks

Asked by: GavT77
Hello. No, they would not be fit for this purpose. They are for flush installation, and not designed to be surface mounted. Thank you for your interest in our appleby brand.

What size rubber grommets will I need?

Asked by: Bealz
Screwfix part number 39957 has 16 x 20mm knockouts which would be the hole size for these grommets therefore we would recommend you use the appropriate grommets to fit this dimension. Thank you for your interest in our appleby brand.

Is this deep enough for a 4mm Cable?

Asked by: Guestie
Hello and thank you for your enquiry. The cable knockouts are 20mm in size on this box, so even with a grommet fitted you will be able to fit in a 4mm cable. Thank you for your interest in our Appleby products.
