<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">That's the link. Yes, that is the big advantage IMHO. If you use a 7/16 masonry drill (as I remember) there is scant clearance between the resultant hole and the 3/8" SS all thread.
I use a liberal amount of Sika 1A caulk around the annular ring and regular SS 3/8" washer on top of that. In southern California we have lots of flat concrete tiles (even easier) as well as S-tiles. I think there still is an app note on their website. Keep
the bit cool by dunking it in a cup of water between holes.<br>

<div>Peter, </div>
<div>Do you have a link to the tile track you referred to. Is it the one spelled Tile "Trac" found at this link >> <a href="http://www.prosolar.com/old_sitepages/tile_trac_index.htm" target="_blank">TileTrac</a></div>
<div>This is nice as it has the flexibility to locate the bolt at the top of the tile when the rafter doesn't line up. But it relies on the bolt going thru the tile at the high point (and some sealant) for keeping water out? </div>

<p class="MsoNormal">I appreciate the suggestion, it sounds like an ideal solution. </p>

<p class="MsoNormal"> I do wonder why you prefer posts when you could use the tile hooks and avoid the extra work and time of cutting and flashing? If it makes for a better attachment structurally and weather-proof wise, then I'm all for it. </p>

None of the below. Use stanchions, also known as power posts. Flash them properly, just like a roof vent, only they will be perpindicular to the roof surface, not vertical.<br>
