M-d 13466 Threshold Insert Seal, Gray Vinyl, 2 X 36-in.

The M-D Threshold Insert Seal is a vinyl replacement insert designed to restore worn or damaged door thresholds to like-new condition. This 2-inch by 36-inch strip fits standard and economy thresholds, creating a tight seal that keeps unwanted air, water, dust, and insects from entering your home. Ideal for residential and light-commercial doors, it eliminates drafts and moisture intrusion without the cost of full threshold replacement.

A properly sealed threshold reduces heating and cooling costs by blocking drafts, protects flooring from moisture damage and mold growth, and prevents pests from accessing gaps at the base of doors. The gray vinyl construction resists weather and wear, maintaining its performance through seasons of use. Installation is straightforward—simply apply soap and water to the insert for smoother placement, then snap it into the threshold frame with no tools required.
