I think that some flashed<br>footings are better than the Unirac L feet or Prosolar's TileTrac foot, but<br>the flashed footings cost a lot more $, and some flashed footing products<br>seem flawed (less watertight) They are asking me to uninstall two<br>commissioned systems from last week, and replace the footings with flashed<br>Fast Jacks, even though the documents detailed the penetration method.<br> I am looking for some good info that supports flexible installation<br>methods, including caulked footings. Our industry has come a long way from<br>the early days of racking on slotted angle iron with steel L-brackets for<br>feet, but those experiences tend to give me confidence in continuing to use<br>caulked footings.<br>Nick Soleil<br>Project Manager<br>Advanced Alternative Energy Solutions, LLC<br>PO Box 657<br>Petaluma, CA 94953<br>Cell: 707-321-2937<br>Office: 707-789-9537<br>Fax: 707-769-9037<br><br><br><br> yy<br><br><blockquote type="cite"><font class="Apple-style-span" color="#144FAE"><font class="Apple-style-span" color="#006312"><font class="Apple-style-span" color="#144FAE"><br></font></font></font></blockquote></div></blockquote></div><br></body></html>
