Overview
Most garage door weathersealing focuses on the bottom of the door, but heat loss, drafts, moisture, and pest entry along the top of the door can be just as significant — especially on doors where the top panel does not sit flush against the header when closed. This flexible vinyl top seal from Action Industries mounts directly to the top panel of sectional garage doors to close gaps at the header, creating a weather barrier that helps improve insulation and protect the interior of the garage year-round.
The seal features a dual-section design — a 1.75-inch rigid section that provides a stable mounting surface on the top of the door panel, and a 0.75-inch flexible section that conforms to uneven surfaces for a tighter fit against the header. No separate retainer channel is required. The seal is designed as a universal fit for most residential and light commercial sectional garage doors and is suitable for both new installations and replacement applications.
Features and Construction
The PL053 is constructed from weather-resistant flexible vinyl in black. The rigid mounting section simplifies installation by providing a firm surface for fastener attachment, while the flexible sealing section bends to maintain consistent contact against the header or wall surface above the door. This dual-section construction allows the seal to conform to minor irregularities in the header surface that a rigid seal would leave exposed.
The vinyl material resists UV degradation, cracking, and warping under changing weather conditions and repeated door cycles, providing reliable performance across seasons without frequent replacement. The seal can be trimmed to the exact width of the door opening during installation.
Applications
This top seal is designed for sectional garage doors where the gap between the top panel and the header or wall above the door allows drafts, water, dust, debris, or pests to enter the garage. It is commonly used on residential garage doors and light commercial overhead doors as a replacement for worn or missing top weatherstripping, or as an upgrade on doors that were never equipped with a top seal. The flexible construction makes it well suited for headers that are not perfectly flat or where the door does not close evenly across the full width of the opening.

Selection Assistance
This top seal is designed for sectional garage doors and mounts to the top panel of the door. It is not designed for rolling steel doors, coiling doors, or doors with built-in header seal systems. Measure the width of the garage door to determine the footage needed, and trim the seal to fit after installation. For help determining whether this top seal is the right product for your door configuration, contact Barron Equipment with a photo of your existing header gap and we can confirm the correct seal.
