Overview
Barron Equipment carries Action Industries T-bulb vinyl bottom weather seals for residential, commercial, and self-storage garage door applications. These USA-made replacement seals feature a rounded bulb profile that presses against the garage floor when the door is closed, forming an effective barrier against drafts, moisture, dust, leaves, insects, and pests at the bottom of the door opening.
The T-end attachment slides into standard 1/4-inch aluminum or plastic bottom seal retainers, making this seal a direct replacement for worn or damaged bottom weatherstripping on most steel sectional doors, overhead doors, Clopay doors, Wayne Dalton doors, and similar brands. The bulb design is a practical alternative to flat T-style seals and works especially well on floors with minor gaps or slight unevenness where a compressive contact point improves sealing performance.
Bulb Sizes
This seal is available in three bulb widths to match the clearance gap between the bottom of the closed door and the garage floor. The 1/2-inch bulb provides a low-profile seal for doors with minimal floor clearance. The 1-inch bulb is the most commonly used size for standard residential and light commercial applications. The 1-1/2-inch bulb offers the most compressive coverage and is suited for doors with wider gaps or slightly uneven floor surfaces.
All three sizes use the same T-end attachment profile and fit the same standard retainers, so the only variable when ordering is matching the bulb size to the gap at the bottom of the door.
Retainer Compatibility
The T-end profile on this seal is compatible with standard aluminum and plastic bottom seal retainers from Action Industries. Before ordering, check that the existing retainer on the bottom of your door has two parallel slots that accept a 1/4-inch T-shaped edge. If the retainer is bent, cracked, or corroded, replacing both the seal and retainer together will deliver the best results. Barron Equipment carries compatible aluminum bottom seal retainers for a complete replacement.
This seal can also be paired with a garage door threshold seal installed on the floor for an additional layer of weatherproofing where the door meets the concrete.
Installation
Open the garage door to a comfortable working height and disconnect the opener to keep the door in place. Pull the old seal out from one end of the retainer channel. Clean any debris, dirt, or corrosion from inside the channel before sliding in the new bulb seal. If needed, apply a small amount of dish soap inside the channel for lubrication.
Feed the T-end edges into both slots of the retainer from one end and work the seal across the full width of the door. A second person helping guide the material from the opposite end makes installation easier on wider doors. Once installed, center the seal evenly and trim any excess from each end. Close the door and verify that the bulb compresses against the floor consistently across the entire opening.

Selection Assistance
Choosing the right bulb size depends on the gap between the bottom of the closed door and the garage floor. If the existing seal is still in place, measure the diameter of the bulb laid flat. If the old seal has already been removed or is too damaged to measure, close the door and measure the visible gap at floor level to determine how much compressive material is needed.
The 1/2-inch bulb is the right choice when the gap is small and the floor is flat and even. The 1-inch bulb covers the widest range of standard residential applications and is the most commonly ordered size. The 1-1/2-inch bulb is the best option when the gap is wider than normal or the concrete floor has minor cracks, slopes, or surface irregularities that require a bulkier seal to maintain consistent contact.
All three sizes are sold by the foot. Enter the total footage needed as your quantity — each order ships as one continuous piece. Measure the full width of the garage door and add a few extra inches for trimming. Standard single-car doors are typically 8 to 10 feet, and double-car doors are typically 16 feet.
If you are unsure which bulb size or retainer type is correct for your door, contact Barron Equipment with a photo or measurement of your existing setup and we will help confirm the right match.
