Cord Grip for a surface mount pattress / back box?

[DPG]

I have never seen a 3 gang metal clad socket back box.
The OP wants to make his existing 3 gang sockets into extension leads I believe.

For flips sake how did I miss that??!!

I'll blame last night's beers

Yeah that was kinda the plan just to use them up, though might just end up buying a power strip and let the moths out of the wallet...

Could you use metal clad sockets and fit stuffing glands in the knockouts? Or would that be a bit industrial?

That wouldn't be an issue, just don't have anything metalclad on hand and was just trying to use some bits up to be tight rather than giving the wallet moths some fresh air lol....

I would go for pvc back box and compression glands… or you could try flog your excess sockets on Facebook or something.

Re. glands, what you want here is secure clamping and you have a choice of actual cord grip bushes e.g. RS PRO, Black Nylon 66, Locating Cable Bush, 11mm Bundle Diameter | RS Components - https://uk.rs-online.com/web/p/cable-separators-bushing/0607897
These don't provide a seal but they do reliably grip the cable.
Or one of the decent glands; I would recommend the Lapp Skintop range which offer good cable retention unlike some of the rubbish stocked by wholesalers. I like the ones with a strain relief tail for this kind of thing. 53111710+53119110 | Lapp SKINTOP M16 Cable Gland With Locknut, Polyamide, 10mm, IP68, Black | RS Components - https://uk.rs-online.com/web/p/cable-glands/3658539

Stuffing glands with normal box or 47mm boxes have grips sometimes
