Concrete inserts to unistrut trapeze with unistrut pipe clamp run up tight to the deck? If you have a little flexibility solid rings to inserts is still pretty short and much cheaper. Short armovers (no hanger needed) rolled up into a 45 or similar to be tight to the deck?

Sent by: "Sprinklerforum" <[email protected]> I am working on a project with a lot of 20x20 rooms in dwelling units. I have a concrete deck so my piping will be exposed. I am trying to find a 20x20 solutions but keep running in to road blocks. Maybe someone has an idea. The way I see it, I need one of the following … I need a residential pendent sprinkler that can be installed with a deflector distance from the deck greater than allowed by NFPA 13 OR I need a residential UPRIGHT sprinkler listed for 20x20 spacing OR I need a listed hanger attachment that will allow me to install 1" branch piping tight to a concrete deck. And go.
