Features & Benefits

Saves time and money by allowing easy installation from the rooftop without disturbing occupants.
Cast aluminum strainer dome and clamping ring that will not rust for long term durability and performance.
U-Flow Seals exceed the ANSI/SPRI RD1 (introduced in 2004) standard for a secure, watertight connection.

Product Use

Hercules RetroDrains are designed to replace existing new construction drains in re-roofing applications. Installed from the roof surface, Hercules RetroDrains are engineered to be installed without removing the existing drain fixture. Hercules RetroDrains have a mechanical seal for direct connection to existing PVC or cast iron plumbing.

As with all building materials, it is the responsibility of the installer to review product use with a design professional to confirm safety, compatibility and acceptance with the roof cover manufacturer and local building codes.
