Tesserack RS gives you over 1.5″ of height adjustment capability. The leveling screw uses the same power drill bit as the lag bolt and is accessible after the modules are mounted, so you can eyeball leveling faster than using a string line or laser level.
Tesserack RS will work with conventional flashing and micro-flashing systems. It’s also compatible with many slate or tile roof anchors. Otherwise, it has all the benefits of the Tesserack Z.
