The SolaRack® Comp Kit is optimally spaced based on local city code and the rail system used.
For measurements related to clearances and roof setbacks, please refer to your local building and safety office or other
authorities having jurisdiction. When using the Comp Kit with SolaRack® Rails, attachments may be spaced
up to 72”. For proper installation, please refer to the
detailed installation guide on page 11.
Lag screw must be
installed in the center of a roof rafter and sealant must be applied under the flashing during installation. Installation must be
preformed by licensed professionals to avoid roof damage. Removing stone gravels and deforming shingles in any way
during installation can and will shorten the lifespan of the roofing. Be sure not to install systems on poor quality or damaged
surfaces.
