Our retrofit plug doors and replacement doors & frames fit most makes of walk-in and come with all the components needed for installation. Give us the walk-through opening (width, height and depth) and tell us cooler or freezer. Measure the frame opening, not the worn door. ### What is a plug door? A door whose insulated slab sets into the opening rather than lying flat against it, with a perimeter gasket that seals all the way around the frame and a sweep across the bottom to the floor or threshold. It is the standard walk-in door format because that geometry seals and stays sealed as the gasket ages. Ours come as a complete door and frame, with an inside casing that secures the exterior frame. ### When should I use a sliding door instead of a swing door? When space restricts the use of a swing-type door, or when the traffic is pallets and forklifts and you need a larger opening. Sliding doors are suitable for interior and exterior applications on coolers, freezers and food processing facilities. Manual is standard; electric operation is also available. ### Are freezer doors heated? Yes. Freezer doors and frames are equipped with a perimeter heater wire connected to a 2″ × 4″ electrical junction box (115 V), so the frame does not ice up and freeze the door shut. Cooler doors do not need it, which is why we ask cooler or freezer before quoting. ### Can I get stainless steel, or a window? Both. 24 gauge 304 grade stainless steel in a #3 finish, or 26 gauge white stucco-embossed galvanized steel, in place of the standard Acrylume; aluminum diamond-tread kick plates inside and out; and view windows in different sizes. ### Can I get locked inside? No. Every plug door carries a glow-in-the-dark inside release handle. You cannot get locked in, even if someone padlocks the latch from outside. ### Do you make other sizes? Yes. The standard sizes are what is on the shelf; we can meet any size opening. Call with the walk-through opening and we will quote it. ## Also worth a look ### [Walk-In Coolers](https://www.frigidcoolers.com/products/walk-in-coolers) Held at 35°F.
