M-D Foam Insert Adjustable Height Threshold

M-D 4-9/16" x 1-3/8" x 36" Silver Adjustable Aluminum Thermal Break Threshold is designed to provide an effective seal for uneven gaps beneath your door, ensuring comfort and energy efficiency. This threshold features an adjustable riser and a thermal break design that is perfect for extreme temperature climates. The thermal break material is strategically placed on the interior side of the doorway, creating a barrier that prevents outdoor temperatures from transferring inside. This helps reduce heat loss and frost buildup on the threshold. In addition to enhancing insulation, it protects your home from drafts, moisture, dust, and insects. Suitable for both new door installations and replacements, this threshold comes with all the necessary hardware for easy installation. It can be trimmed to the desired length using a hacksaw before installation. For optimal sealing, it can be paired with a door sweep or an under-door seal to keep your home comfortable and protected year-round. Model Number: 43822
