Thermwell DT36/72A Aluminum Threshold Kit 3.75x72 in

Product Description

The THERMWELL DT36/72A is a super deluxe brushed aluminum threshold kit designed for door bottom sealing in residential and light commercial applications. Measuring 3.75 inches wide by 72 inches long, this low-rug profile threshold features vinyl inserts on both the top and bottom surfaces for tighter sealing performance. The aluminum construction stands up to heavy foot traffic, making it a reliable choice for high-use entryways. A licensed contractor or experienced installer will find the 72-inch length suitable for standard and slightly wider door openings. The package quantity is 4 units per order.

This threshold kit is used at exterior door openings where a low-profile seal is needed between the door bottom and the floor. The low-rug design accommodates low-clearance situations where thicker thresholds would interfere with door swing or floor coverings. The dual vinyl inserts compress against the door bottom to reduce air infiltration and debris entry. It is typically installed by carpenters, general contractors, or building maintenance personnel working on entry door weatherization projects.

Installation Notes

Installation is typically performed by a carpenter or general contractor using basic hand tools including a drill, screws, and a hacksaw or metal-cutting blade if length trimming is required. Measure the door opening width carefully before cutting the threshold to final length. Remove the door from its hinges if needed to allow proper placement and fastening at the sill. Ensure the vinyl inserts are fully seated before securing the threshold to avoid gaps that reduce sealing effectiveness.
