Frequently Asked Questions

How do you measure a window on a catalog or booklet?

Always measure the window by having the flap at the ceiling. When giving the dimensions for the window, the smaller number is given first for a horizontal window (ex. 1 3/4 x 4 3/4) and the larger number is given first for a vertical window (ex. 4 3/4 x 1 3/4) based on the flap being at the ceiling.
