I assume you are asking how they are strapped Larry?
I used a unistrut union with two holes. In the center I drilled a hole for a 1/4-20 to go through to a spring nut. Fortunately, the predrilled holes are distanced perfectly to hold the Mineralcs.
The change in depth also happened to exactly be the depth of a box offset, so we were able to use our offset benders to get the exact depth.
Unfortunately, they told us everything was going to get painted, so I used some green unions that we had at the shop. But I think I’m the only one that has noticed it.
