I decided it would not hurt to add an S hook for additional support.
Photo shows the mounted Conduit using EMT Strap and a single S hook (size unknown).The installer will need to install the S hook and slide the conduit up to engage it. Using the Single S hook, the installer will need a screw driver to pry the S hook leg to the side in order to ratchet down the bolt. Once this is done the installer will need to bore through the pilot hole into the conduit for the conduit screw. I bought 1.5" Bolt to mount the straps since we are adding additional washers.
From Top, using one washer under the strap and one above.

An alternative would be to use two smaller S hooks. This is easier, but lacks the strength of the larger single S hook.
Completed Bat house. The shingles I had did not match and were 
the 3 tab. I decided the architectural or high profile shingle would look better and bought those. All are completed and the bat design is placed randomly on the bathouses.
Hindsignt: I should have stained the area that is exposed at the 1/2 inch vent, before assemblying. Just a matter of how it looks, the bats should not mind. However, my wife does!!
Final weight.28.8 Lbs..................... All there, except bottom strap...
