Overview
This L-shaped plastic bottom seal retainer provides a lightweight, budget-friendly way to mount weatherstripping to the bottom of residential and commercial garage doors. The 1-1/2 x 1-3/8 inch profile is designed for garage doors approximately 1-3/8 inches thick, making it compatible with a wide range of standard overhead doors, sectional doors, wood garage doors, and vinyl garage doors.
Where aluminum retainers are the go-to for heavy commercial use, this PVC plastic alternative delivers corrosion-free performance at a lower cost. It is a lightweight, more economical version of aluminum bottom seal retainers from Action Industries — ideal for property managers, maintenance teams, and DIY homeowners looking to weatherproof their garage doors without overbuying on materials.
Compatible with T-end or T-style rubber seals, vinyl seals, or bulb seals from Action Industries, this retainer accepts the same weatherstripping profiles used by its aluminum counterparts. That means you can pair it with the seal material that best fits your environment — rubber for temperature extremes, vinyl for standard conditions, or bulb seals for uneven floor surfaces.
Features and Benefits
This retainer is a cost-effective solution for mounting garage door bottom seals to commercial and residential garage doors. PVC plastic construction resists rust, corrosion, and warping — problems that can shorten the life of lower-grade metal retainers in moisture-prone environments. The lightweight material also makes handling and installation easier, especially on multi-door projects where technicians are working overhead or at floor level for extended periods.
When installed at the bottom of the door, retainers enable easy installation and maintenance of bottom weather seals that keep out small pests, harmful weather, drafts, and outdoor debris like leaves. Because the retainer channel accepts standard T-style profiles, replacing a worn seal down the road takes minutes — slide the old seal out, slide the new one in, no retainer removal required.
Each box contains 10 retainers, making this product a practical stocking item for facilities managing multiple doors or for service crews completing batch replacements across a property. Three standard lengths cover most common garage door widths with minimal cutting.
Applications
This plastic bottom seal retainer is designed for any application where a garage door bottom seal needs to be mounted on a 1-3/8 inch thick door panel. Common applications include:
Works for both residential and commercial applications — from single-bay home garages to multi-unit commercial facilities. It is particularly well suited for self-storage properties, apartment complex garages, and light commercial buildings where dozens of doors may need weatherstripping at once and cost per unit matters.
The plastic construction also makes it a strong choice for coastal, humid, or high-moisture environments where metal retainers may corrode over time. For facilities that already use Action Industries weatherstripping, this retainer integrates directly into the existing seal system with no compatibility issues.
Selection Assistance
Before ordering, confirm that your garage door panels are approximately 1-3/8 inches thick. This retainer is specifically profiled for that dimension and will not mount securely on thicker or thinner door panels. If your door is closer to 1-3/4 or 2 inches thick, you will need a different retainer size.
Next, select the length that matches your door width. Available options include 8 feet 2 inches, 16 feet 4 inches, and 18 feet 4 inches. For non-standard door widths, the PVC material can be easily trimmed on-site with standard cutting tools — no specialty equipment needed.
If you are deciding between this plastic retainer and the aluminum version (A1315), the choice comes down to environment and budget. Aluminum retainers are generally preferred for commercial and industrial applications due to their durability and ability to withstand heavy use. Plastic retainers offer a lightweight and cost-effective alternative that can be easily cut on-site for custom installations. For standard residential and light commercial use, the plastic option delivers the same seal compatibility at a lower price point.
This retainer does not include the weatherstripping material. You will need to select a compatible T-style rubber seal, vinyl seal, or bulb seal separately. Contact the Barron Equipment team if you need help selecting the right retainer size or pairing it with the correct seal for your garage doors.
