Cord Grip for a surface mount pattress / back box?

[overskilled]

I know this is a bit of an odd one, so bear with me, I have an idea in mind, but many of the power strips I see are either a) crap b) stupidly expensive, c) lack mounting holes or d) all of the above.
So given I have a fair number of 3 gang sockets and back boxes (bought for a job cancelled at last minute), it got me wondering if other than using a stuffing gland, if there was such a thing as a cord grip for a plastic surface mount pattress/back box?
Anyone ever heard of such a thing?
Thanks (no I haven't quite yet lost my marbles...there is a method to my madness I swear honest!)

I remember old Volex surface boxes having a cable grip, but not seen anything like those recently.

47mm cooker pattresses usually have a cord grip incorporated in them.

Hmmm thats interesting, Suppose I could just go 2 gang rather than 3 (never going to use the 3s so I was just going to use them up on this project tbh....

Maybe use these with a stuffing gland?

Only ever seen 47mm surface boxes come with a cable grip

Never seen a 25 or 35mm with a cable grip

That said I rarely use those brittle plastic boxes anymore , I normally use a pvc box and a stuffing gland

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

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.
