Pemko 434ARL Full Mortised Automatic Door Bottom | Black Sponge EPDM Insert
The Pemko 434ARL Full Mortised Automatic Door Bottom is a premier architectural solution designed for high-performance sealing and complete concealment. Ideal for high-end wood and metal doors, this heavy-duty drop seal is mortised directly into the bottom of the door, providing a sleek, invisible finish that preserves the aesthetic of upscale condos, luxury hotels, and modern commercial offices.
Equipped with a resilient Black Sponge EPDM insert, the 434 Series provides a superior, slightly compressible barrier against air, light, sound, and smoke. This model features a specialized low closing force mechanism, ensuring the door remains easy to operate and making it a top choice for projects that must comply with ADA and ANSI A117.1 accessibility standards.
Key Features & Performance
- Concealed Full Mortise Design: Completely hidden within the door leaf to provide a clean, flush look without compromising the architectural integrity of the opening.
- Black Sponge EPDM Seal: Highly flexible at both high and low temperatures, this material resists deterioration from oily substances and offers a superior seal against uneven surfaces.
- ADA Compliant Operation: The "smoother action" mechanism requires low closing force, satisfying ADAAG 2010 requirements for accessible door assemblies.
- Precision Drop-Bar Actuation: The jamb-contacting plunger ensures hinge-side actuation, which prevents seal skidding and protects your flooring from unnecessary wear.
- Field Adaptable: Provided at NET length and can be trimmed by up to 2" in the field (stock sizes) to ensure a perfect, custom fit on-site.
