What is the best method/stick stainless steel nameplates to the door sill please?

Thanks in advance.....

I'd give Sika a go. Rough up the back of the plates first to aid adherence. I use it for all sorts of things now including sticking down the coping stones on swimming pools

Thanks for that, had to look this one up as never heard of it. Sooo much on the market for nearly everything these days, good to get a heads up with something that's been tried & tested..

double sided 3m adhesive pads have kept mine in place for 14 years.

Any one know of a good fit, metal sill plate, that can be purchased online please? I remember there was a group buy for laser etched 20vt ones all these years ago, apologies I'm reminiscing here over some whiskey

Aye that's the ones I purchased some time ago & have been sitting in my shed ever since. Never got round to fitting them, there was always something else needed doing, you know how it is. I'll be fitting them when my Coop comes home. Sorry of no help to yourself.

Just for a wee while I thought you had miss spelled Whisky, until I realised where you come from......

.

which place would you choose on the threshold of the slat -?

Neither of those, I would place them in the middle

I’m with you Dave, middle it is.
