Has anyone had any experience of this?
A source of supply for these dished plugs in Melbourne? Once you could get this sort of thing at Repco but no longer.

I don't know what welsh plugs are but they look like frost plug holes to me///.If the block freezes ..they pop out instead of you block cracking..very common in Canada..Can pick them up at Canadian tire the next time you are by..
Merry Christmas..
