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.

OlyFlow RetroDrains are designed to replace existing drains in reroofing 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.
Superior productivity. Superior performance.
