Measuring 3.75 inches wide by 36 inches long, this high-boy profile threshold sits taller than standard units, providing an effective seal at the base of the door. It ships with a replaceable deluxe extra-high vinyl insert that cushions door contact and helps block drafts and moisture infiltration. The extruded aluminum construction delivers long-term resistance to foot traffic, corrosion, and seasonal expansion. This threshold is appropriate for installation by general contractors, carpenters, and experienced DIYers working on residential entry door weatherproofing projects.\u003c\/p\u003e\n\u003cp\u003eThe DT36HRHA is suited for standard 36-inch residential entry doors where a high-boy profile is needed to close gaps between the door bottom and the subfloor or finished flooring surface. The replaceable vinyl insert extends the service life of the unit — when the insert wears, it can be swapped out without replacing the entire threshold. This makes it a practical choice for high-traffic doorways in single-family homes, apartments, and light commercial entryways. This product corresponds to model RV36H.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeavy extruded aluminum construction resists corrosion and long-term wear under foot traffic\u003c\/li\u003e\n  \u003cli\u003eHigh-boy profile provides extra height to seal larger gaps at door base\u003c\/li\u003e\n  \u003cli\u003eReplaceable deluxe extra-high vinyl insert extends service life without full threshold replacement\u003c\/li\u003e\n  \u003cli\u003e36-inch length fits standard residential entry door openings\u003c\/li\u003e\n  \u003cli\u003eDesigned for residential entry door weatherproofing applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation threshold for standard 36-inch residential entry doors requiring a high-boy aluminum profile with a vinyl insert.

Remove the existing threshold and clean the door sill area before fitting the new unit. Ensure the door closes evenly against the vinyl insert without excessive drag that could stress the door hardware.
