Door and Opening Designation
Door or Opening designations should be used on Floor Plans to relate each Door or Opening (not designated by other means) to a "Door Schedule" (upper number in circle) and to the "Frame Details" (lower number).
Hardware Set Numbers should appear on each Door and identifies the Hardware required for each Door which is specified in the Project Manual.
Doors of the same size and quality should have the same number as well as Frame Details which are identical shall have the same number.
