Can I buy a collar or gland with adjustable aperture for a 100mm dia cat5e bundle through plasterboard ceiling ?

[a546345]

I have a bundle of cat5e/cat6 and AV cables to go through a plasterboard ceiling down into a patch cabinet in my house. Above the ceiling is an accessible loft. I could drill a 110mm hole in the ceiling, put the cables through and then seal the gaps up with spray foam.

Is there a gland or conduit that allows me to seal the hole but let me unseal it later if I need to run more cables?

Thanks!
