Oval Grommets for 15mm boxes

[Micktw68]

Anyone have a supplier . Not used a shallow box for years and i cant find the grommets for love nor money

20mm grommets will fit

Don't the 20mm ones fit them, if you squish them? i.e. 16mm oval radius = 20mm circle radius

Alternatively, if the KOs are not really knock-outs, but with a sort of bent-over flange, which is smooth, I wouldn't bother putting a grommet on them, as there's no sharp edge

Crenellated grommet strip, maybe?

I thought 20mm fitted....if too big, just cut a bit out of one.

As #3, most have rolled edges. No need for grommit. And if you do use a grommit, the hole becomes too small to fit many cables in.

Bit snug, but squeezed in in the end.

Only top entries are rolled, though. There are other, various knockouts too.

Remember...... for donkeys years they came with a slimline grommet?

I use a Wallace, I know it's late and I'm tired....................and my mind is working in a very strange way.

I always thought Grommet needed to go on a diet

Is this a wind up ? the circumference is the same oval or round.

Perhaps, but the area of the hole will be smaller, ergo the available space for cables is smaller.
