Flat Base	Straight Base

Slope Base

All mounts have a square bottom, round top, and flashing to simplify installation.

To Order: For slope-base mounts, please specify pitch: _1/12-_11/12 in increments of _1/12. To determine pitch, use an angle indicator or divide rise by run (see illustration). For instance, if your roof rises 5" in 12" of horizontal space, your pitch is _5/12.
