Norlake 172153 Door Frame Air Block 5.812 Inches

Product Description

The NORLAKE 172153 is a door frame air block designed for commercial refrigeration applications. Air blocks seal gaps in walk-in cooler and freezer door frames, preventing warm air infiltration and maintaining interior temperature stability. This component is a direct replacement part used by refrigeration technicians and commercial kitchen service pros to restore proper door frame sealing when original blocks crack, compress, or fall out of position. The listed dimension of 5.812 inches reflects the block width or span, making accurate measurement of the existing opening essential before installation.

This air block is suited for commercial walk-in cooler and freezer door frame assemblies manufactured by NORLAKE. It is typically installed during routine maintenance, door overhaul, or when visible air leakage around the door frame indicates a failed or missing air block. Proper sealing reduces compressor run time and helps maintain food safety temperatures in commercial food service environments.

Installation Notes

Installation is typically performed by a qualified refrigeration technician or commercial appliance service professional. Before servicing, disconnect power to any associated door heater circuits if present and allow the door frame area to reach ambient temperature. Remove the old or damaged air block fully before seating the replacement to ensure a proper fit and seal. Verify the 5.812-inch dimension against the existing frame channel before installation.
