Sizing the Screen
If the door opening is smaller than 36" (914 mm) wide and 80 9/16" (2,047 mm) high when using the Low Bottom Rail 3 or less than 81 3/16" (2,062 mm) high when using the High Bottom Rail 4 , the Screen must be cut.
NOTE: Actual Unseen components are designed with offset dimensions to fit a standard opening (see dimensions above); therefore parts will not measure the same as the doorway dimensions. To fit a smaller opening, determine the Length to be Cut from the components by calculating the difference between your doorway measurements and the standard width and height provided above.
Determining Cut Size for Screen Housing
Important: The cut size of the Screen Housing depends on whether the Low Bottom Rail 3 or High Bottom Rail 4 is selected. Ensure that the
correct formula is used (see page 9 for Bottom Rail selection). For Screen Housing with Low Bottom Rail
Use the following formula:
(Measured Height) [Length to be cut off]
80 9/16” (2,047 mm) - [ | ] = |

For Screen Housing with High Bottom Rail
Use the following formula:
(Measured Height) [Length to be cut off]
81 3/16” (2,062 mm) - [ | ] = |
