Measure Window Depth
Measure the depth of the window frame. If less than 2.4 inches or an obstruction (lever, crank) is present, we recommend choosing outside mount.
Measure Window Width
Order Width = The Smallest Window Width measured at Top, Middle, and Bottom.
Measure Window Height
Order Height = The Highest Window Height measured at Left, Center, and Right.
Order at the exact opening size with no deductions. We'll deduct 1/8 inch (3.2 mm) during production to ensure proper installation.
