If you are trying to bid and bid tight you might need one of your men to look at the prints with you, steel drawings, architectural, etc., think stub 90 first, can start the run from anywhere and go in both directions, ending with spinning the box on or use of the proper hub.
Haven't priced a 4" in a bit but bet I can beat the price using labor the majority of times. 2 men $75hr one hr. $150 what's the fitting cost?
