[BusNit]

No unistrut. I went to a local solar supply shop (SanTanSolar.com) and they showed me their racking. In fact, all of their stuff is on display in their showroom. Very helpful people. This was all foreign to me. I used K2 solar racking with aluminum mounting feet. They have proprietary mounting clamps for the solar panels. I feel very good about the installation's security. All drilled holes were filled with Dicor before and after along with final coating over entire bolt assembly which is not pictured. I chose this route of racking since I wanted the rain water and dirt to flow normally and not be trapped against strut. Not only that, but if your K2 rails are not exactly straight or in line with one another, it doesn't matter! Installation was so easy and one of the most anxiety causing parts of the job. Took me an afternoon to get the rack done and the following day to get the panels up.
