The unistrut is the more heavy duty version from home depot.. I believe there were 2. Are you referring to the 14x14 picture frame i made to raise the AC up 3/4in? I don't have any pictures of the that.. But it's simply a pice of 1x2 pine, that i made into a box. I used silicone between the box and the roof, and screwed it down. Then used eternabond on to completely water tight the joint.
