  • The best way to know if you can use Argco Flex Drops on your project is to submit on them with the submittal package you can request from me.
  • Do I have to use elbows on my sprinkler drops? Generally you do not as long as you’re maintaining the minimum turn radius.
  • Every Flexible Fire Sprinkler Connection has a maximum amount of 90 degree turns, refer to the product data.
  • When installing in suspended ceilings, make sure to check if your jurisdiction requires a structural engineer’s stamp verifying that the suspended ceiling meets ASTM C 635 AND C 636 . (San Francisco is one example)
