Pemko 411APKL32 Automatic Door Bottom 32 Inches

Product Description

The PEMKO 411APKL32 is a full mortise automatic door bottom designed to create a weathertight seal at the base of a door. When the door closes, the internal mechanism automatically drops the seal into contact with the threshold or floor surface, then retracts when the door opens. The housing and drop seal assembly are constructed from anodized aluminum and PemkoPrene, providing durable performance in both interior and exterior door applications. At 32 inches in length, this unit fits a standard 2 foot 8 inch door. Mounting hardware is included. Installation is straightforward for door hardware specialists, finish carpenters, and commercial door contractors.

This door bottom is intended for use in residential and commercial applications where energy efficiency, weatherization, and draft control are required. The full mortise design requires a routed channel in the bottom edge of the door, making it a clean, flush-mounted solution. It is well suited for new construction and retrofit projects where air infiltration, dust, or light gaps at the door base need to be eliminated. The mill finish aluminum blends with standard commercial door hardware finishes.

Installation Notes

Installation is performed by a qualified door hardware technician or finish carpenter. The full mortise design requires precise routing of the door bottom edge to accept the housing - verify door thickness and bottom rail dimensions before cutting. Confirm the door is fully removed or secured before mortising. Consult applicable building codes for weatherization requirements in your jurisdiction.
