Hi everyone, well on the way to finishing wiring, any ideas on where to source rubber grommets for wiring through 6mm thick fibreglass??
15mm and 20/25mm dia holes?
Many thanks in advance,
Roman

Let there be light!

6mm width grommets will be hard to source they are designed for thin sharp edges up to 2mm as a rule, sleeving may be an easier option if you have larger holes with gaps around the loom the use something like silicon sealant.
I tend to drill the fibreglass so the wire just goes through if it is too thick.

Thanks Snoopy, after a little investigation this evening, I came across a product called
VERSIMOULD, anyone used it to make grommets?

Or Liquid Moulding silicon Rubber (room temperature vulcanizing RTV silicon/rubber) might be worth a go at moulding my own!

Think I am getting there!!!

I use a short length of split rubber hose of the right ID and a tight fit on the OD, held in place either side of the hole by a Tyrap.

This sort of thing readily available in many diameters etc from various out lets.

Beat me to it Paul, that's what I was going to recommend.

Big benefit I have found is if you go slightly oversize getting that extra cable through a year later is easy.

They are meant to fit in the panel in a groove at the top so where the glass is particularly thick, ie everywhere on a Doon, I trim the bottom lip of the groove off and mastic them in

Thank you everyone, I will use the bulkhead grommets. Sound idea and good value too.

Or give me some sizes and I'll 3d print you some.

That would be great, thank you and I will be in touch.
Some more photos and I did manage to get 2x 6mm grommets for free as samples !! Still 3 more holes to grommet
