Pemko 412CRL Surface Mounted Automatic Door Bottom | Clear Anodized Aluminum
The Pemko 412CRL Surface Mounted Automatic Door Bottom is a heavy-duty, high-performance solution for retrofitting doors that require superior protection against the elements. Unlike mortised versions, this surface-mounted automatic door bottom is installed directly onto the face of the door, making it an ideal choice for existing commercial or residential doors where high-level sealing is needed without complex machining.
Equipped with a Black Neoprene EPDM insert, the 412 Series excels in extreme environments. This resilient material remains flexible at high and low temperatures and is specifically designed to resist deterioration from oily substances. When the door closes, the jamb-actuated plunger triggers a "smoother action" positive seal, dropping the gasket to eliminate gaps and block out noise, light, and drafts.
Key Features & Performance
- Surface-Mounted Versatility: Easily installs on the exterior face of the door; perfect for soundproofing and weatherizing existing entryways in commercial buildings and high-traffic facilities.
- High-Grade Neoprene EPDM Seal: A slightly compressible, durable rubber-like material that provides an airtight barrier against smoke, fumes, and moisture.
- Precision Actuation Mechanism: The drop-bar is actuated from the hinge side to prevent seal skidding and door hang-up, ensuring a positive seal every time the door is latched.
- Adjustable Protection: Effectively seals gaps up to 3/4" (with a recommended gap of 1/2"), significantly reducing air leakage and sound transmission (ASTM E 90-2009).
- Field Trimmable: Provided at NET length and can be trimmed by up to 2" in the field to ensure a perfect fit for your specific door width.
