When the door closes, the mechanism automatically lowers a PemkoPrene sealing element to contact the floor or saddle, blocking air, sound, light, dust, and moisture infiltration. When the door opens, the seal retracts flush with the door face, preventing interference with floor coverings or traffic. At 30 inches in length with a mill finish aluminum body, this unit is suited for interior and exterior door applications in commercial and residential construction. Architectural millwork installers and door hardware professionals are the primary trades who specify and install this product.\u003c\/p\u003e\n\u003cp\u003eThis automatic door bottom is intended for mortise installation into the bottom rail of a door, making it appropriate for new construction and retrofit projects where a concealed, low-profile seal is required. It fits standard door widths at the 30-inch nominal size, commonly referenced as 2 feet 6 inches. Typical applications include office doors, corridor doors, hotel guestroom doors, and residential entry doors where weather sealing, acoustic attenuation, or code-required smoke and draft control is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFull mortise design mounts inside the door bottom rail for a concealed, flush appearance\u003c\/li\u003e\n  \u003cli\u003eAutomatic actuator mechanism lowers the seal on door close and retracts on door open\u003c\/li\u003e\n  \u003cli\u003ePemkoPrene sealing element provides contact seal against threshold or floor surface\u003c\/li\u003e\n  \u003cli\u003eMill finish aluminum housing resists corrosion and suits a wide range of door finishes\u003c\/li\u003e\n  \u003cli\u003e30-inch length fits standard 2 feet 6 inch door width applications\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 1.5 pounds for straightforward field installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for full mortise door bottom applications on standard swing doors requiring an automatic drop-seal mechanism.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a door hardware technician or finish carpenter. The door must be mortised to the correct depth and width at the bottom rail before the unit is set and fastened. Verify door thickness and bottom rail depth are sufficient to accept the mortise housing before cutting. Follow the door manufacturer's template and the applicable building or fire code requirements when installing door bottoms on rated assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Length\u003c\/strong\u003e: 30 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Length\u003c\/strong\u003e: 31 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 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: 1.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Mill Finish\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: PemkoPrene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Full Mortise\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuation\u003c\/strong\u003e: Automatic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSales Unit\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: 411APKL30\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PEMKO","offers":[{"title":"Default Title","offer_id":51562466541874,"sku":"411APKL30","price":69.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/90971dcdd310e9f5ba82c0732e9772a1_5b88a9f8-c920-411e-b89d-52be8bcae864.jpg?v=1786477391","url":"https:\/\/voomisupply.com\/products\/pemko-411apkl30-full-mortise-automatic-door-bottom-30-in","provider":"Voomi Supply","version":"1.0","type":"link"}
