① Measure the Width

1. Measure the inside width at the top (A), center (B), and bottom (C).

2. Use the smallest measurement.

3. If the measurement includes 1/16" or 1/32", round down to the nearest 1/8".

Example: 36 11/16" should be entered as 36 5/8".

② Measure the Height

1. Measure the inside height on the left (D), center (E), and right (F).

2. Use the largest measurement.

3. If the measurement includes 1/16" or 1/32", round up to the nearest 1/8".

Example: 42 5/16" should be entered as 42 3/8".

③ Measure the Depth

At the top of the window opening, measure from the front edge of the window frame to the nearest obstruction (G).

If the depth varies, use the smallest measurement and confirm that it meets the product's minimum inside-mount depth requirement.

Please Note

Enter the actual inside width and height of your window opening as your order dimensions.
