Determines Hinge Location & Maximum Window Dimensions
Please select the maximum window size of you PIAD, as related to the maximum span or length of the hinged side and adjacent sides. The first letter specifies the maximum span of the hinged side of your PIAD, while the second letter specifies the maximum span of the adjacent sides.
For example, if you require a window size not exceeding 12″ tall and 24″ wide, and prefer the hinge to be on the left or right side, select PIAD Size AB. For the same window size with the hinge on the top or bottom side, select PIAD Size BA.
