ProSolar FastJack

Quick and strong flashable roof stanchion for roof-mounted solar panels.

The Prosolar FastJack solar panel roof mount attachment provides a quick and strong installation solution. The patented design places the bolt directly under the stanchion post where it provides the most support. This feature allows standard roof flashings to lay flat on the roof deck.

The patented design of the FastJack® is the most innovative, efficient and cost-effective tool of it's kind. The FastJack has been laboratory tested to provide 2,359 pounds of strength using only a single lag bolt (included). The removable post allows flashings to be slipped over the base without damaging surrounding composition shingles. The standard FastJack's larger base allows for stanchion heights of up to 7-1/2", making it desirable for snow load installations.

ProSolar FastJack Benefits

  • Removable post makes installation on existing roofs/retrofit quick and easy
  • Patented design locates the lag bolt directly under the stanchion providing superior strength values
