Plate in box frame

[Jon_Brooke]

I need to mount a deep plate (almost a dish) inside a box frame.

Ideally I'd like some sort of transparent plastic clips that will hold the edges of the plate and can be mounted individually directly to the mountboard behind the plate - I can put a piece of ply behind the mountboard so I have something firm to fix to.

I'm guessing this product must exist but not found it so far.

Any advice please.

I prefer the no visible attachments look. I've used these traditional plate fixings a few times, very strong bond, I feed the metal loop through to the back of the mountboard and tape it in place.
