Specification Sheets:
The examples of the eyebrow dormers in the spec sheet are only twelve custom versions of the system. The system can be ordered for any pitch house roof from 6/12 to 14/12 or any fractional pitch in between. The pitch of the three models (IE. 34, 36, 38) will always be 4/12, 6/12, 8/12 pitch respectively.

For Example:
Our customer calls and would like the model #34 on a 11 1/4 /12 pitch.
We would recommend model #38 to create the elegant eyebrow valley.
If our customer has a 6/12 pitch we would use model #34.
If our customer has an 9 1/2 /12 pitch we would use model #36.
