’nest’ properly into door frame, during fitting and trim-
ming of the new door. The old door latching mechanism
and acrylic glass is to be reused if possible.

tact with either exterior paint, composite shell,
interior trim or acrylic surfaces. It is permissible

hesive around mating area. Follow manufacturer’s in-
