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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFits door frame channel at 5.812 inches to match OEM dimensions\u003c\/li\u003e\n\u003cli\u003eBlocks conditioned air from escaping around the door frame perimeter\u003c\/li\u003e\n\u003cli\u003eDirect OEM replacement part for NORLAKE walk-in refrigeration units\u003c\/li\u003e\n\u003cli\u003eHelps reduce energy loss caused by door frame air infiltration\u003c\/li\u003e\n\u003cli\u003eSupports consistent interior temperature maintenance in cooler and freezer applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM replacement air block for NORLAKE commercial walk-in cooler and freezer door frame assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation 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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5.812 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Commercial walk-in cooler and freezer door frame\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Type\u003c\/strong\u003e: Door frame air block\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORLAKE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 172153\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORLAKE","offers":[{"title":"Default Title","offer_id":51161658556722,"sku":"172153","price":191.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/306257816.jpg?v=1778878319","url":"https:\/\/voomisupply.com\/products\/norlake-172153-door-frame-air-block-5-812-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
