I'm looking for a type of strike plate to replace ones I (stupidly) got rid of. They were originally installed in the mid 80's into metal door frames.
From memory, it was a metal box that sits inside and is screwed into the hole in the frame, with a small lip.
I've tried searching online and all the normal hardware shops without any success.
If you know the name of them or any other places I could try looking please please let me know!
Thank you
