Inside Mount
Windows can be slightly uneven. Follow these steps for the best fit.
Width (W)
Measure the inside of your window frame at the top, middle, and bottom. Use the smallest measurement and round down to the nearest size to get your order size.
Height (H)
Measure the inside of the frame on the left, middle, and right. Use the largest measurement. When ordering, choose a size that matches or exceeds this measurement.
Depth (D)
A minimum of 2 3/4" is required. If less, choose an outside mount.
