Designed for existing through-wall/side-wall or scupper drainage pipes, the aluminum and stainless steel drain components provide durability and compatibility with single ply, BUR and modified bitumen roofing systems. Scupper RetroDrains are available in 3-, 4-, 5- and 6-inch sizes and include a U-Flow mechanical seal.
Features & Benefits
- Pre-punched drain flange provides stable attachment to the wall and roof deck.
- 0.060-in. thick drain strainer is easily secured to the drain body with four stainless steel wing nuts and provides protection against rooftop debris.
- Simple and easy installation saves time & labor.
- U-Flow Seals exceed the ANSI/SPRI RD1 standard for back flow prevention.
Scupper Thru-wall RetroDrains are designed to replace existing drains in re-roofing applications and 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.
