Missing Handle Set

I'm afraid this information doesn't tell me anything about the handle set or what hardware the door uses. This only tells me who made the glass, which doesn't actually have anything to do with anything else on the door.

The only way we can accurately identify hardware is to use the original parts as a reference. As your parts are missing, it will be very difficult, if not impossible. I'm happy to try my best but we need some kind of reference to get started. A photo of the location where the handle installed would be a good start, as well as a photo of any related hardware that interacted with the handle.
