Overview
The P-bulb bottom seal is a replacement weatherstrip designed for garage doors that use a P-bulb style aluminum retainer mounted along the bottom edge of the door. When installed, the flexible bulb profile compresses against the garage floor as the door closes, sealing the gap beneath the door against drafts, moisture, dirt, insects, and outdoor debris. This seal is a popular weatherstripping style for Genie and Overhead Door brand garage doors and is compatible with most two-inch single-layer rolling steel doors commonly found in mini-warehouse and self-storage applications.
Manufactured by Action Industries, this replacement seal is made from a strong, flexible grey vinyl compound that maintains its sealing performance through repeated door cycles and across a range of temperatures. It is sold by the foot in custom lengths or in 100-foot reels for contractors, property managers, and multi-door projects.
Features and Specifications
The P-bulb seal is constructed from a durable, flexible vinyl compound designed to compress evenly against the floor surface and recover its shape after each door cycle. The grey color provides a clean, neutral appearance that blends with most residential and commercial door frames. The seal slides into the existing P-bulb style aluminum retainer — no additional hardware, adhesive, or retainer replacement is needed when the existing retainer is in good condition.
The P-bulb attachment profile has a diameter of 0.195 inches. The overall seal measures 1.5 inches wide by 1.87 inches tall. These dimensions should be compared with the existing seal before ordering to confirm a proper fit. For additional weather protection at the threshold, the P-bulb seal can be paired with a garage door threshold seal.
Door Compatibility
This P-bulb bottom seal is designed for use with garage doors that have a matching P-bulb style aluminum retainer. It is a popular weatherstrip profile for Genie and Overhead Door brand garage doors, and is also compatible with most two-inch single-layer rolling steel doors — sometimes called pan doors — commonly used in mini-warehouse and self-storage facilities.
Compatible Genie models include 188, 189, 281, 288, 381, 390, 391, and 399. Compatible Overhead Door models include the 180, 280, and 390 series. Door components may vary over time, so the existing retainer profile should always be confirmed before ordering.

Selection Assistance
Before ordering, compare the attachment profile of your existing seal with the P-bulb design to confirm compatibility. The existing retainer must be a P-bulb style aluminum retainer for this seal to fit properly. If the retainer is bent, corroded, or damaged, it may need to be replaced at the same time as the seal for best performance. Measure the garage door width rather than relying on the old seal, which may have stretched or shrunk over time.
