Hager 770SAV 3' Sill Sweep with Integrated Rain Drip & Nylon Brush
The Hager 770SAV is a multi-functional commercial door sweep designed to provide maximum protection for exterior entryways. This specialized hardware combines a high-density nylon brush seal with an integrated rain drip guard, creating a dual-action barrier. While the brush seals the gap at the threshold to block drafts and pests, the rain drip shield deflects water away from the bottom of the door opening, preventing moisture from seeping under the door during heavy rain or snow.
Dual-Action Weatherproofing and Life Safety
The Hager 770SAV is engineered for high-performance environmental control and safety compliance. The black nylon brush insert is designed to remain permanently flexible, ensuring it won't become brittle in freezing temperatures or lose its shape under high heat. This unit is UL Classified and fire-tested in accordance with UL10C, making it a code-compliant solution for Category J doors. Additionally, it meets ASTM E283-91 standards for air and smoke infiltration, providing a critical seal for fire-rated exterior openings.
Durable Mill Aluminum Construction
Constructed from high-quality extruded mill finish aluminum, the 770SAV is built for long-term durability in high-traffic commercial settings. The 3-foot length is ideal for standard commercial doors and can be field-trimmed for a precision fit. The housing features slotted screw holes, allowing for easy vertical adjustment to ensure the brush maintains constant contact with the threshold or floor surface.
