FAQ Knowledge Articles

The size of the screen for the Ultimate Inswing French Doors need to be adjusted if the door is ordered with an ADA Sill because of the difference in sill height compared to the standard sill.

The screen needs to be ordered on a separate line by an adjusted Rough Opening (RO):

Adjusted Rough Opening Height = Actual Rough Opening Height + 0.363

For example, a Clad Ultimate Inswing French Door CN 3068 with an ADA Sill has an Actual Rough Opening Height of 81.5625.

81.5625 + 0.363 = 81.9255.

81.9255 is the Adjusted Rough Opening Height to use when ordering.

The following comments will need to be sent in with the order.

  • Adjust RO height for unit with ADA Sill
