Large grommets needed

[Eric12]

Hi does anyone know where I can source any larger round grommets ? I will be drilling a hole in 100 × 100 trunking so guess around 75mm hole. I've seen larger grommets before but they were a different material to rubber, they were like rubber but had fibre in them, a bit like bicycle tyre material; dont know if these come in a strip or were round. I dont want to use that plastic strip like found in consumer units as there not much lip on them to hold it in place. Can anyone help; cant find anything over 32mm and not even sure if theres any standard grommet sizing over 32mm !

Flexible Grommet Strip maybe your best option

Ordered some grommet strip (Edging strip) now, so should be fine for this number

I find it difficult to believe that someone with their 2360 pts 1 & 2 along with their NVQ 3 does not know how to provide mechanical protection for a 75mm hole.

The stuff that won't stay in place can be fixed in no time with a little cyanoacrylate. If you're in a real hurry, a quick spray of activator bonds it immediately.

I've found that sort of strip great for larger openings and heavier gauge steel. It's not so good with smaller openings and, while I'm not a big fan of them, light castellated strips tend to work better on those.

I’d go with a large bush and lock ring as well. Got a bucket of various sizes from old strip outs.

Grommet strip never stays in place.

I've been using this purchased from Amazon for years now. It's very secure.
