Hercules RetroDrains, the industry’s most popular retrofit drain, are available in 75 mm, 100 mm and 150 mm sizes and with a variety of options to support any project, including OMG’s exclusive Vortex Breaker Strainer Dome, which can increase flow by up to 2.5 times (see Hercules-Plus).
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 standard for a secure, watertight connection.
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.
