Engineered for compatibility with existing through-wall, side-wall, or scupper drainage pipes, this system is an excellent solution for reroofing projects that require drain replacement. It installs directly from the roof surface and is specifically designed to integrate with existing plumbing—eliminating the need to remove current piping or fixtures—while providing a secure, watertight seal to both the roof system and the existing drainage infrastructure.
Performance and built to last, heavy-duty spun aluminum. Incredible durability, making it the smart choice for distributors, contractors and building owners alike. Installs quickly with compression bolts - no adhesives required - for a secure, long-lasting fit, even in aged or irregular piping.
