As the door closes, the internal mechanism drops the sponge neoprene seal into contact with the floor surface, then retracts it automatically when the door opens. This action prevents air infiltration, drafts, dust, and sound from passing beneath the door. The unit is finished in mill finish aluminum and sized at 36 inches for standard door widths. It is typically installed by finish carpenters, door hardware specialists, or commercial contractors working on interior or exterior door assemblies in residential and commercial applications.\u003c\/p\u003e\n\u003cp\u003eThe 411ARL36 is suited for use on commercial or residential doors requiring a mortised installation where the door bottom mechanism is recessed into the bottom rail of the door. Typical applications include office entry doors, corridor doors, hotel guestroom doors, and residential exterior doors where weather sealing, draft control, or acoustic attenuation is a priority. The sponge neoprene seal provides a compliant, compressible contact surface that accommodates minor floor irregularities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFull mortise design installs recessed into the door bottom rail for a clean, low-profile appearance\u003c\/li\u003e\n  \u003cli\u003eAutomatic drop-and-retract mechanism activates on door close and retracts on door open\u003c\/li\u003e\n  \u003cli\u003eSponge neoprene seal provides compressible, draft-resistant contact with the floor surface\u003c\/li\u003e\n  \u003cli\u003eMill finish aluminum housing resists corrosion in typical interior and light exterior environments\u003c\/li\u003e\n  \u003cli\u003e36 inch length fits standard commercial and residential door widths\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation door bottom for full mortise door applications requiring an automatic seal mechanism in a 36 inch door width configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires routing a mortise pocket into the bottom rail of the door to recess the housing flush with the door face. A licensed door hardware installer or experienced finish carpenter should perform the mortising and fitting work. Verify door bottom rail thickness is sufficient to accept the housing depth before cutting. Follow applicable building codes and manufacturer instructions for mounting hardware torque and seal adjustment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.54 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Sponge Neoprene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Mill Finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Full Mortise\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation\u003c\/strong\u003e: Automatic Drop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\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: PEMKO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 411ARL36\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PEMKO","offers":[{"title":"Default Title","offer_id":51563250712882,"sku":"411ARL36","price":74.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35940e1326265d082d5c76dc2f5eb202_61ff4ac3-8f0a-4b3b-820a-fda7f3366bc0.jpg?v=1786494065","url":"https:\/\/voomisupply.com\/products\/pemko-411arl36-full-mortise-automatic-door-bottom-36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
