32DR Through Bolt Adapter

The 32UB is designed is for adapting a plumbizer to a mast arm or pedestrian pole by bolting to a surface where there is not a welded 1 ½” threaded hub to accept the 45B. It is attached by drilling through a pole and using a threaded rod with an acorn nut on the opposite side. Also two 11D castings can be used back to back on the same pole using the same threaded rod.
