Per the data sheets, you don't need to sprig on 3" pipe
Individual pipes and conduit 4 inches (102 mm) diameter or less 3-inch
(DN80) pipe size or less will not require sprigs).

I haven't used them either, but I did do some light reading on the topic
recently;
Cons: must be raised (sprig's or candle sticks) above piping 3" and
larger
Pro: eliminate some obstruction rules vs pendent ESFR heads
Customer gains more storage room (sprinkler head in upright
position vs pendent)
Just a few comments...

I Found an Up-Right ESFR K17 Tyco,. but..
Does anyone know when can I use It?,.. if the proper branch line could
be an
obstruction.
Normally or never I have used an Esfr Up-right.
