Replace the door, not the walk-in
Prehung & ready to install
Every door ships hung in its own frame with hinges, gasket, and hardware already mounted. Set it in the opening, fasten it to the wall, and you're back in business.
Built to your measurements in Detroit
Each door is manufactured to your exact opening size at our Detroit factory — not trimmed down from a stock size. Custom dimensions are standard, not an upcharge.
Direct-from-manufacturer pricing
You buy straight from the factory that builds your door. No distributor markup, honest lead times, and financing available.

Walk-In Cooler & Freezer Replacement Doors from Detroit, Michigan
ELT Cooler Doors manufactures walk-in cooler replacement doors and walk-in freezer replacement doors at our factory in Detroit, Michigan, and ships them nationwide. For more than 18 years, our family-owned shop has built custom walk-in doors for restaurants, grocery stores, convenience stores, florists, and food-processing facilities that need a worn-out door replaced without tearing apart the box around it.
Every door is prehung in its own frame and built to the exact dimensions of your opening, so it installs over your existing wall panels in about an hour — no panel replacement, no downtime. We replace doors on any brand of walk-in, including Kolpak, Amerikooler, Master-Bilt, Nor-Lake, US Cooler, and Bally, and we build swing, sliding, and glass French door configurations for both coolers and freezers.
Because we are the manufacturer, you buy factory-direct: no middleman markup, real lead times, and a team that can answer measurement questions before you order. Financing is available, and every door ships fully assembled from Detroit to anywhere in the continental United States — or pick yours up at our factory.
