A standard frame is designed for most modern walk-in cooler openings. A plug frame is the correct choice for older walk-in coolers where the original opening was cut for a plug-style door. ELT Custom Coolers offers both options to ensure a proper drop-in fit for your existing opening.

In freezer applications, a heated frame — also called a heated jamb — is strongly recommended to prevent frost build-up, ice-up, sweating, and door-stick at the door opening. ELT Custom Coolers offers heated frame and heated plug frame options on select walk-in freezer replacement doors, particularly for lower-duty and high-traffic freezer environments.

A prehung door ships with the frame already assembled, making it a true drop-in replacement. There is no on-site door or frame fabrication required. This reduces installation time significantly, minimizes the need for specialized labor, and ensures the door and frame are properly matched for a secure, energy-efficient seal from day one.

Sliding doors are the right choice when forklift, pallet jack, or cart pass-through access is required. They provide a wider opening footprint without the clearance swing radius of a hinged door. ELT Custom Coolers offers sliding cooler and freezer doors from 36"x78" up to 12'x12', including an electric power sliding option for high-cycle automated doorways.

Yes. The Kason 402 Easimount strip curtain sets are compatible with both swing and sliding walk-in cooler and freezer doors. They serve as a secondary barrier to maintain cold air when the primary door is open during high-traffic periods. Installing strip curtains can reduce compressor run-time by 20–40% on high-cycle doorways and support food-safety temperature compliance.

ELT Custom Coolers offers both. Their 8'x8'x8' walk-in cooler or freezer box is a turnkey solution including insulated panels and a prehung door, configurable for cooler or freezer duty. It is ideal for new build-outs, ghost kitchens, small-format retail, and secondary box additions. Refrigeration packages are sold separately.
