Norlake 129471 Threshold Strip Flat 36 Inch Door Seal

Product Description

The NORLAKE 129471 is a left-hand flat threshold strip designed for commercial refrigeration door assemblies. This component seals the gap at the base of the door opening, preventing warm air infiltration and helping maintain consistent interior temperatures. Measuring 36 inches in length with a 1/8-inch adjustment tolerance, it provides a fitted barrier at the floor-level threshold. The flat profile suits standard door frame configurations found in walk-in coolers and freezers. Installation is typically performed by a commercial refrigeration technician or facilities maintenance professional as part of door seal replacement or unit restoration work.

This threshold strip is intended for commercial refrigeration applications, including walk-in coolers, walk-in freezers, and related cold storage enclosures. The left-hand orientation corresponds to the hinge and swing configuration of the door assembly. Units in food service, grocery, and cold storage environments subject to frequent door cycling benefit from periodic threshold seal replacement to maintain energy efficiency and food safety compliance. The 6-designation in the part number references an internal NORLAKE configuration code consistent with specific door frame series.

Key Features

Installation Notes

Installation should be performed by a qualified commercial refrigeration technician or experienced maintenance professional. Disconnect power to any electrically interlocked door components before beginning work. Verify door swing direction and hinge side before ordering to confirm left-hand orientation matches the existing assembly. Inspect the door frame and floor surface for levelness to ensure the 1/8-inch adjustment range is sufficient for the application.
