Measuring 1.25 inches wide by 36 inches long, this insert fits directly into compatible adjustable threshold tracks, restoring the door-bottom seal that reduces drafts and moisture intrusion. Installation requires no special tools in most cases, making it a practical field repair for contractors, property maintenance technicians, and experienced DIYers working on exterior door assemblies. The vinyl construction is flexible enough to conform to minor floor irregularities while maintaining consistent contact with the door bottom.\u003c\/p\u003e\n\u003cp\u003eThis threshold insert is intended for use in adjustable Macklanburg Duncan threshold bodies only. It is a direct drop-in replacement for the original vinyl insert in those assemblies, making it well suited for residential exterior door maintenance and light commercial applications where the original threshold frame is intact but the insert has cracked, compressed, or degraded over time. Sold in a package of 12 inserts, this SKU is appropriate for service contractors managing multiple units or building maintenance programs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.25 x 36 inch profile fits adjustable Macklanburg Duncan threshold tracks\u003c\/li\u003e\n  \u003cli\u003eGray vinyl construction is flexible and weather-resistant\u003c\/li\u003e\n  \u003cli\u003eDrop-in replacement design requires no threshold body removal\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 12 supports multi-door or multi-unit service calls\u003c\/li\u003e\n  \u003cli\u003eRestores draft and moisture seal at the door bottom without full threshold replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement vinyl insert for Macklanburg Duncan adjustable threshold models only.

Before servicing, ensure the door is closed and secured. Remove the existing insert by sliding or prying it out of the threshold channel, then press or slide the new RV46H insert into place along the full length of the track. Verify the door closes with consistent contact along the insert before returning the threshold adjustment screws to the original position.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vinyl\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: THERMWELL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: RV46H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FROST KING","offers":[{"title":"Default Title","offer_id":51559796080946,"sku":"RV46H","price":69.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f11b6f866decc4a8aa3908a0bab8749.jpg?v=1786441333","url":"https:\/\/voomisupply.com\/products\/thermwell-rv46h-vinyl-threshold-insert-gray-36-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
