Make certain a wall receptacle is available close
to the hole location or make arrangements to

Determine the size of wall opening by adding
1/8″ to the height and width of the case.
Measure height from the top of the case to the
bottom of the rail.
Place the case in the wall opening and secure
the bottom rail, case sides and top with 12

Finish the Wall Opening
Caulk all four sides on the outdoor side of the case to prevent moisture from getting through to the

the outside of the building.
