Hager 552S 5" Lipped Threshold with Vinyl Insert | Mill Aluminum
The Hager 552S is a wide-profile lipped threshold engineered to provide a robust weather barrier for commercial and residential exterior openings. Featuring a 5-inch width and an integrated vinyl insert, this threshold creates a high-compression seal against the bottom of the door, effectively stopping drafts, moisture, and dust. Its specialized lipped design makes it a top choice for openings utilizing specialized hardware or those requiring a distinct stop at the sill.
Optimized for Surface Vertical Rod Exit Devices
The Hager 552S is more than just a weather seal; it is specifically designed for use in conjunction with the bottom rods of surface-applied vertical rod (SVR) exit devices. The lipped profile provides the necessary engagement point for secure latching, ensuring that fire-rated or high-security double doors remain firmly closed. With an overall height of 3/4", this threshold is ideally suited for doors with a 1/2" to 5/8" undercut, providing a snug, energy-efficient fit.
Extreme Cold Weather Performance
Built to handle the toughest climates, the Hager 552S features a premium vinyl seal that remains fully flexible in temperatures as low as -40°F. This ensures that the gasket won't crack or lose its shape during deep-freeze conditions, maintaining the building's thermal envelope year-round. The mill finish aluminum base is naturally corrosion-resistant, providing a durable foundation for high-traffic entryways.
