[Closed] Door hardware - what's this called?

Non circular ones are called strike plates.

Shoot bolt keep?

A deadbolt plate

Keep.
Locating plate.

That is a flush bolt strike plate,

I'm pretty sure that would have had a large ball-bearing behind the plate, with a spring behind that, I guess they're called spring catches? Had them on doors all over the house once upon a time.

I guess from the photo, that's a bolt plate in a threshold, not on a door.

Going from the picture, are you after this sort of thing?

Gold ish coloured plate with a hole in for me door... At a guess. What do I win?

That's exactly what it's for. There's already a security bolt attached and I want a second floor plate so I can keep the door in the open position without the toddler closing it!

Its a keep for a bolt which is mounted in the floor.

Ironmongery direct are a decent outfit to start from.
