Sliding Glass Door Handle Set

The screws on handle measure 6 5/8" and were attached to the external keyed handle with black plastic mounts. the handle opening on the door is 7 1/4" high by 3/4" wide with the lock opening pretty low and 2" center hole. Notice the exterior handle, it sat on the outside of the opening edges and sets the lock back off flush 1/4". There are no other idents on this other than "Japan". The plastic parts crumbled and I am looking for a replacement that is keyed and will cover precut hole. The interior hole side gets filled with the handle assembly, but the exterior handle is the problem as I need it to cover that 7 1/4" x 3/4". Any help id appreciated.

Hi, The inside part is pretty standard, its the outside part (pic on right) that needs to cover the opening 7 1/4". The outside concave handle rests on the outer side edges (see the marks on pic) of the opening so it won't fall through (see pic). I know its a tough one and I can't find a manufacturer Id anywhere.

Your help is appreciated.
Thanks,
Mark

I would drill through the spot where the plastic inserts were and put in a binder post to reuse the current handle.

A nut and bolt can also be loosened or removed from the outside. Not desirable.
