2) Side outlet roof drain configurations for joists that are 16" on center minimum

This section applies when you have limited space between the roof and ceiling and need to use a side outlet roof drain. The side outlet roof drain incorporates the 90 degree bend into the drain body, thereby requiring less vertical installation space.

Pipe runs parallel to the joists -

  • 90 degree adjustment

3) Side outlet roof drain configurations for joists that are 24" on center minimum

This configuration can also be used when installation space is minimum. With the joists at 24" minimum spacing, you have ample space to configure your pipe runs in almost any direction. This versatility becomes useful when you need to maneuver around objects such as electrical fixtures, conduit, mechanical ducting etc. in the joist bay.
