Description
The M-D 36-inch door threshold insert with vinyl seal is a durable upgrade that helps create a tighter seal at the base of an exterior door. Constructed from extruded aluminum with an integrated vinyl sealing strip and vinyl caulking strips under the legs, this threshold insert minimizes airflow and helps reduce moisture migration where your door meets the floor. It installs at the foot of single or double doors to improve energy efficiency and comfort by closing gaps that allow drafts, dust, and small debris to enter. Commonly used on entryways, patio doors, and utility doors, the 36-inch length suits standard openings and the U.S. origin underscores its domestic manufacture. The clean aluminum profile provides a low-profile transition while the vinyl components maintain a resilient seal for everyday use.
