Pemko 411ANBL 36" Full Mortised Automatic Door Bottom
The Pemko 411ANBL 36" Full Mortised Automatic Door Bottom is the premier choice for architects and facility managers who require a high-performance seal that remains completely invisible. Specifically engineered for architectural excellence, this heavy-duty automatic door bottom is mortised into the door, ensuring the sleek aesthetic of upscale condos, luxury hotels, and modern commercial offices is never compromised.
Equipped with a high-density Black Nylon Brush insert, the 411 Series is the ultimate solution for sealing gaps over irregular surfaces. The specialized drop-down seal mechanism is engineered for a "smoother action" positive seal, preventing seal skidding and ensuring your door operates effortlessly while providing a total barrier against the elements.
Key Features & Performance
- Concealed Full Mortise Design: Fits seamlessly into a prep at the bottom of the door, making it invisible when closed—perfect for decorative and high-end wooden doors.
- Black Nylon Brush Seal: Features densely compressed nylon filaments that conform to irregular surfaces like carpet, stone, and grout lines better than standard rubber gaskets.
- Automatic Drop-Bar Actuation: The jamb-contacting plunger triggers the seal only when the door is fully closed, sealing gaps up to 3/4" without causing door hang-up or friction during the swing.
- Field Trimmable: This 36-inch door bottom is provided at NET length and can be trimmed by up to 2" in the field for a precise, custom fit.
- Universal Compatibility: Suitable for both 1-3/4" and 1-3/8" thick doors (Note: For 1-3/8" applications, please specify the K411 end plate kit).
