Sealing Consumer Unit Knock Outs

[charlie76]

Evening folks. What are you guys using on to seal 38mm knock outs consumer units? Seems 38mm blind grommets are rare as hens teeth or at least no one stocks them... Any advice appreciated.

Either a gland or failing that bus and locking with some sealant gunned into the gaps.

I don't use boards with 38mm knockouts, but the knockouts I do knockout I surround with trunking to maintain IP ratings where necessary.

Don't forget to bond the screws Daz

using a 40mm+ hole saw drill 2 holes in some old steel trunking and use these with a 6mm roofing bolt to sandwich 'em together
