The pole blocks are shown and the lines on the walls where the bulkhead plate will sit on the oak corner brackets.

One of two blowers are seen here along with the linear bearing and the 3/4-10 threaded rod with the unfinished mirror clip. Between them is an anchor bolted to the side of the box with a 3/8-16 threaded stud sticking out....

As seen here, using one of the secondary cage stanchions as a truss pole, the truss will pass through the pole block (and bulkhead plate not shown but will sit on top of the oak coner bracket) and get threaded onto the anchor stud. The block will be tightened for a two point attachment of the truss. The poles are very sturdy in this arrangement unlike a single pole block attachment....

The pole blocks are getting attached after things are leveled and a plumbline hanging down from the apex of two truss poles. The three fans are seen which will blow across the mirror to eliminate the surface heat layer....
