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 75 mm, 100 mm, 125 mm, and 150 mm sizes and include a U-Flow mechanical seal.
Features & Benefits
- Pre-punched drain flange provides stable attachment to the wall and roof deck.
- 1.52 mm 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.
