The THERMWELL A62/36WH is a white door sweep designed to seal the gap at the bottom of exterior and interior doors. It combines an aluminum mounting channel with a triple-seal neoprene rubber bottom to block drafts, dust, insects, and light infiltration. The sweep measures 2 inches wide by 36 inches long, providing full-width coverage across standard door bottoms. Screws pass through the rubber and the aluminum channel simultaneously, creating a secure mechanical attachment that resists shifting over time. This product is suited for installation by general contractors, maintenance technicians, and experienced DIYers working on weatherization or building envelope upgrades.
The A62/36WH is appropriate for residential and light commercial applications where door bottom sealing is required. It is commonly installed on entry doors, utility room doors, and garage access doors where air sealing and pest exclusion are priorities. The 36-inch length fits most standard single door widths and can be cut to length in the field with a hacksaw or tin snips. The white finish suits painted or primed door faces in residential construction.
Designed as a standard replacement or new-installation door sweep for residential and light commercial single doors with a 36-inch or narrower door width.
Installation does not require electrical shutoff or specialized trade licensing. Attach the sweep to the interior face of the door bottom using the provided or appropriate sheet metal screws, driving fasteners through the rubber and aluminum channel as designed. Confirm door clearance before installing to ensure the sweep contacts the threshold without impeding door swing. Field-trim with a hacksaw or aviation snips if the door width is less than 36 inches.
