    This Pemko #4131 Automatic Door Bottom lowers a rubber seal when the door is closed to prevent infiltration of light, sound and drafts. The high quality mechanism of the door bottom ensures smooth action when the seal is lowered. 

    It is designed for regular duty usage, in residential or low-frequency usage commercial settings.

    Seals: Available with a PemkoPrene™, Sponge EPDM and Sponge Silicone insert.

    • EPDM is comparable to Sponge Neoprene, though has significantly better performance and is more environmentally friendly! It has great sound control properties and is resistant to solvents.
    • PemkoPrene™ has a multi-point contact design and is great for uneven surfaces such as a tiled floor or carpet. Due to the way PemkoPrene™ is manufactured, it is not as firm as sponge silicone and allows for more leniencies.
    • Sponge Silicone 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. The seal lowers to fill gaps up to 3/4".

    Mounting: This automatic door bottom can be surface mounted or semi-mortised applied to the face of the door.

    Installation: Installation instructions, end plates and screws provided. Screws are colored to coordinate with casing.

    How it Works

    The high quality automatic mechanism consists of an aluminum case which surrounds a moveable drop-bar seal. The drop-bar seal is actuated by a plunger which contacts the door jamb as the door is closing, forcing the drop-bar seal down against the floor / threshold. The plunger requires low "Feather Touch" closing force to actuate the drop-bar seal. The plunger causes the seal to always actuate on the hinge side first, which prevents the seal from skidding along the floor/threshold while the door is being closed. Door hang-up will not occur!
