This item is being discontinued - limited quantity on hand

The Hager 779S is a professional-grade U-shaped door bottom designed to provide a comprehensive perimeter seal for 1-3/4" thick commercial and residential doors. By wrapping around the bottom edge of the door, this aluminum housing offers superior protection against air infiltration, smoke, and moisture compared to standard surface-mounted sweeps. The multi-finned vinyl insert creates a tight barrier that significantly improves energy efficiency and building comfort.

Engineering for Performance and Fire Safety

The Hager 779S is built for reliability in high-traffic and extreme environments. The high-grade vinyl gasketing is engineered to remain fully flexible in temperatures as low as -40°F, preventing the seal from becoming brittle or cracking in winter conditions. Additionally, this product is UL10C fire tested and classified for use with Category J doors, making it a vital component for maintaining the integrity of fire-rated openings in schools, hospitals, and office buildings.

Precision Adjustment and Versatile Lengths

Available in 3-foot (36"), the 779S can be easily trimmed for a custom fit. The aluminum housing features slotted screw holes, allowing the installer to fine-tune the seal height to compensate for uneven thresholds or floors. To achieve the best performance, a 5/8" clearance is recommended between the bottom of the door and the floor surface.
