Rough Opening Dimensions
Each unit requires a separate opening in the drywall. Each pair of
units will have a 2x4 stud separating them. The trim frames cannot
be butted together. There will be a space between edges of trim
frames of approximately 3/4” when 2x4 studs with drywall separate
the mailboxes.
Calculation Of Space Required for Multiple Units
For overall width of mailbox installation, add all of the stud spacing
and subtract ¾”. For overall height of units, see the dimension chart
