Inside Mount:
• Your window casing depth must be at least 1 ¾".
• Measure and provide the exact inside width and height of your window.
• We will make the necessary deductions to ensure a perfect fit.
Outside Mount:
• Measure from the outer edge of the window, including all moldings.
• Add at least 2" to the height.
• If there are no moldings, add 2" or more to each side to reduce light gaps.
• These will be your final product dimensions.
• For doors, we always recommend choosing an outside mount.
