M-d Building Products 43302 Door Bottom Weatherstrip 36 in

Product Description

The M-D BUILDING PRODUCTS 43302 is a replacement door bottom weatherstrip designed to seal the underside of a 36-inch door against air infiltration, dust, water intrusion, and insects. The unit is constructed from aluminum with a vinyl insert and comes pre-trimmed to fit 36-inch door widths straight out of the package. Installation relies on 3M adhesive technology, so no drilling, screws, or pilot holes are required. This product is suited for residential or light commercial entry doors and is typically installed by a contractor, handyman, or knowledgeable property owner during routine weatherization work.

This weatherstrip is appropriate for exterior door bottoms on standard 36-inch residential and light commercial doors where a low-profile, adhesive-mounted seal is preferred. It is a practical replacement for worn or missing door bottom seals on inswing or outswing doors and is commonly used during energy efficiency retrofits or seasonal weatherization projects. The aluminum body provides durability while the vinyl insert maintains consistent contact with the threshold surface.

Key Features

• Pre-trimmed aluminum body with vinyl insert fits standard 36-inch doors without cutting
• 3M adhesive backing eliminates the need for drills, screws, or pilot holes
• Seals against air, dust, water, and insects at the door bottom
• Quick peel-and-stick installation, typically completed in under 5 minutes
• Brown finish for compatibility with common door and threshold colors

Compatibility

Designed as an adhesive-mount replacement door bottom weatherstrip for standard 36-inch exterior or interior doors where no mechanical fasteners are required or desired.

Installation Notes

Installation does not require power tools or fasteners. Clean and dry the door surface thoroughly before applying the adhesive backing to ensure proper bond. Measure the door width before installation and trim the strip if needed to achieve a precise fit. This product is appropriate for DIY installation but should be applied in accordance with any applicable local building energy codes.
