Item Number: 9431
Manufacturer: OMG Roofing Products
Manufacturer Part No: RACDX3

The RAC Deluxe RetroDrain is constructed of aluminum & stainless steel for durability and designed for use with single ply, BUR and modified bitumen roofing systems. The drain features an extra large flange for positive attachment of the roof flashing membrane, a recessed metal clamping ring for roof termination and proper drainage, along with an oversized drain strainer to minimize damming. The patented RAC Backflow Compression Seal is compatible with PVC or cast iron leader pipes and is available in 3-in., 4-in., 5-in., and 6-in. sizes.

Features & Benefits

  • Drain flange insures consistent, stable attachment to the substrate outside of the existing drain bowl and positive attachment of flashing membrane.
  • Strainer dome features a low profile base to promote drainage and the large diameter provides added flow capacity and minimizes damming.
  • 9-in. long drain stem accommodates most existing field conditions with custom drain pipe lengths available for quick turn elbows or deep existing drain bowls.
  • The aluminum clamping ring is recessed into the drain flange to maximize drainage and is secured to stainless steel studs.
  • The RAC Backflow Compression Seal is quickly activated at drain flange level and protects the roofing system and building contents from water backup damage.
  • Saves time and money by allowing easy installation from the rooftop without disturbing occupants.


OlyFlow RetroDrains are designed to replace existing drains in re-roofing applications. Installed from the roof surface, OlyFlow RetroDrains are engineered to be installed without removing the existing plumbing or fixture while providing a watertight connection to the roof system and the existing plumbing.

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