The primary and differentiating feature of Maxell Airtight Products (M.A.P.) and flashing materials is its “Quick and Easy Installation”. The MAP-S34 is the “Heavy-Duty” workhorse of Maxell’s M.A.P. system. While previous models focus on plumbing supply and small waste lines, the S34 is specifically designed for the large penetrations found in a building’s envelope, such as main sewer stacks and mechanical exhaust vents.

The 3″ and 4″ pipe sizes are standard for high-volume air and waste management, making the MAP-S34 essential for:

1. Main Sewer Stacks
2. Dryer Vents
3. Radon Mitigation Systems
4. Fresh Air Intakes
5. Large Roof/Wall Plumbing
