Papillon Universal Garage Door Bottom Threshold Seal – 16.5 ft EPDM Weather Stripping

Papillon Universal Garage Door Bottom Threshold Seal Strip offers a versatile, weatherproof solution for the gap at the bottom of most garage doors. When installed, it forms a tight profile about 1/2 inch tall, creating a barrier against pooled water, wind-driven rain, snow, and leaves. In everyday use, this seal helps keep the garage cleaner, drier, and quieter, while contributing to a more comfortable space for projects, workshops, or parking. The kit can run up to 16.5 ft long (5 meters) and is 3.5 inches wide, allowing a single piece to cover most common thresholds and still leave room to trim for a precise fit.

Crafted from premium EPDM rubber, the seal holds up across a wide temperature range—from the deep cold of -40°F to the scorching heat of 284°F. With proper installation, it should resist cracking, drying out, or losing shape, maintaining flexibility through seasonal shifts and daily traffic. Real-world benefit includes reduced dampness near metal walls and components, which can help limit condensation and rust in the door sill area.

DIY installation is straightforward and requires no professional help. The seal ships slightly longer than advertised to ensure ample material for your project, and you can cut it to length to match your door precisely. Note that adhesive or sealant is not included; you can choose a mounting approach that suits your door and toolkit.
