Jason, It's funny that you bring this up because it is an issue that we constantly face on commercial new construction. Commercial roofers want 8 plus for their lead jacks plus the cricket often takes several inches above the deck. Many folks in the Bay Area are using Hollaender rail

Greetings Fellow Wrenchies, With all the racking options out there today, are there any stand outs in terms of quality and installation time. We are in the process of evaluating our racking system and with all the options its a little mind boggeling. Mahalo in advance! * James B Rudolph*

I'm wondering if multiple 7 Unirac 2-piece Stand-Offs cylinders threaded together with all-thread would be a structurally sound solution. I'll pass that option by the engineers... Still hoping for an off-the-shelf solution... J ason On Tue, Sep 10, 2013 at 4:38 PM, August Goers

This is a similar solution to the Hollaender foot but from Unirac: http://www.civicsolar.com/product/unirac-403216s Cutting pipe isn't that big of a deal, but you need to have threaded pipe for this product compared to the Hollaender fitting which uses set screws. More food for thought.
