Norlake M18903 Custom Threshold

Product Description

The NORLAKE M18903 is a custom threshold component designed for use with walk-in cooler and freezer installations. Thresholds serve as the transition piece at the base of a walk-in door opening, bridging the gap between the floor panel and the surrounding floor surface. This part provides a structurally sound, weather-tight seal at the entry point, helping to maintain temperature integrity inside the refrigerated space. Installation is typically performed by a commercial refrigeration technician or walk-in unit service professional as part of a new installation or door assembly replacement.

Custom thresholds like the M18903 are used in commercial refrigeration applications where standard threshold sizes do not meet the specific dimensional requirements of the installation site. This component is well-suited for food service, cold storage, and light industrial environments where walk-in coolers or freezers are in use. As a custom-specified part, it is built to fit a defined opening configuration rather than a universal footprint.

Key Features

• Custom-sized threshold for non-standard walk-in door openings
• Designed to maintain a tight seal at the base of refrigerated enclosure entries
• Manufactured by NORLAKE, a recognized name in commercial walk-in refrigeration equipment
• Intended as a direct replacement or new-installation component for walk-in cooler and freezer door frames

Compatibility

Designed as an OEM-style replacement threshold component for NORLAKE walk-in cooler and freezer door assemblies where custom sizing is required.

Installation Notes

Installation should be performed by a qualified commercial refrigeration technician or experienced contractor. Power down any associated door heater circuits and ensure the refrigerated space is not in active operation before beginning threshold work. Verify the threshold dimensions match the door opening exactly before securing in place, as custom parts are not typically returnable or field-modifiable. Local building and mechanical codes may apply depending on the installation environment.
