Always measure width by height

For Surface Mount Panel:

• Measure the inside width – divide opening width by 2 and add 2”
• Measure the inside height – add 4” to the height

For Recess Mount

• Panel coverage will be reduced by ½” from width and height of the opening

Considerations

• If you are in the design stage ensure that there is clear space for the installation of these shutters
• Exterior lights, bands or other that may affect installation
• Flat leveled, smooth surface required
