Window
frames will sometimes vary from side to side (width) and from
top to bottom (height). When measuring the inside dimensions
of the frame in which the RollAway™ screen will fit, be sure to
measure the width of each frame at the top, middle and bottom.
For each height measurement measure at the left and right side
of each frame opening  see diagram A to the left. Measure
to the nearest 1/16". When ordering always use the smallest
of each dimension.
EXAMPLE:
In diagram A the measurements you should record would be 21"
x 48", as 21" is the smallest width and 48" is the smallest
height. A 1/16" deduction in width and height demensions
are necessary for a proper fit. Therefore, we would manufacture
your RollAway™ Screen to measure 20 15/16" x 47 15/16" in
order to arrive at the list price go to the next largest size:
24" x 48"
