    Pemko #411 Automatic Door Bottom has a drop down seal which is automatically lowered when the door is closed to seal the gap. Casing is made of aluminum mill, is fully mortised and will not affect the appearance of the door, ideal for decorative doors, upscale condos, dormitories, commercial buildings and luxury hotels. This model is compatible with 1-3/4" and 1-3/8" thick doors, however, different end plates are required for each door. Please select from options above.

    When choosing a seal it is essential to determine the purpose for sealing and the floor surface beneath the seal.

    • Sponge EPDM is comparable to Sponge Neoprene, but is made of more Eco-friendly material and has overall superior performance. Specifically, it has great sound control properties. 
    • PemkoPrene™ is great for uneven surfaces such as a tiled floor or carpet (Nylon Brush Seal is a great option in this aspect, too). Due to way PemkoPrene™ has great overall performance, except in the area of soundproofing. All three options remain effective in a wide range of temperatures and can be used on external doors.

    Insert Replacement: This seal is designed to last through much usage, however if necessary a replacement seal can be purchased - see our Sponge Rubber Replacement for Pemko #411

    Installation: Installation instructions, end plates and screws provided.

    Compliance Details of Mortised Automatic Door Bottoms with Rubber Seals

    ANSI Codes:

    • Sponge EPDM: R3G324, R3G325
    • PemkoPrene: R3G324, R3G325
    • Silicone: R3E324, R3E325

    The Automatic Door Bottom utilizes a concealed flat spring mechanism which is activated upon opening and closing of the door. A brass plunger is compressed when the door is closed to automatically drop the seal, starting from the hinge side first. The seal is raised when the door opens. This motion ensures a smooth drop without a drag, even on an uneven surface. It is compatible with a door saddle or against the floor. The door bottom is built from durable materials that are meant to last. It has been tested through 5 million cycles!
