The primary and differentiating feature of Maxell Airtight Products (M.A.P.) and flashing materials is its “Quick and Easy Installation”. The MAP-S56 is the “Extra-Large” solution in Maxell’s M.A.P. system. This is the largest standard size in the series, engineered to handle the massive penetrations typical of commercial mechanical systems and heavy-duty residential exhaust.

The 5-inch and 6-inch sizes are rarely used for standard plumbing supply, but they are the industry standard for high-volume ventilation, making the MAP-S56 perfect for:

1. Commercial Kitchen Exhaust
2. Whole-House Ventilation
3. Industrial Conduits
4. Large Dryer Vents
5. Stormwater Drainage
