I would pull the UL listing for the 78 and read it, if it says what the catalog says your AOK. Any hanger or attachment listed for fire sprinkler systems is assumed to meet all of the NFPA requirements for load. That is why the minimum desk thickness is 18ga.

Hi Thom,I am using the Tolco 78 and its listing allows this application. Do you think this application gets around the NFPA '99, 6-2.1.3 attachment to the vertical part of the decking? A pull test was done and it made it to 300 lbs I think the issue preventing me from using this is the limitation by the SEOR to 50 lbs max on any attachment to the decking. The 250 lb factor is the killer here.
