A standard frame walk-in cooler door is designed for most modern walk-in box openings. A plug frame door is engineered for older walk-in coolers where the original opening was cut to accept a plug-style door insert. ELT offers both frame types across their swing door lineup, ensuring compatibility with virtually any existing walk-in box configuration.

Yes, in many freezer applications a heated frame—also called a heated jamb—is strongly recommended. Without it, moisture from warm ambient air condenses and freezes at the door frame, causing frost buildup, ice-up, door-stick, and compromised seals. ELT offers heated frame and heated plug frame options on their walk-in freezer replacement doors for reliable, frost-free operation.

Sliding doors are the right choice when forklift, pallet jack, or cart access is required, or when traffic volume through the cooler opening is high. ELT's sliding cooler doors are available in 18 sizes from 36"x78" up to 12'x12' with an electric power option on the largest configuration, making them ideal for distribution facilities, commissaries, and large-format grocery operations.

Strip curtains are the most effective doorway accessory for reducing energy loss. The Kason 402 Easimount Strip Curtain Set creates a secondary PVC barrier that keeps cold air in and warm humid air out during high-traffic open periods. Studies show strip curtains can reduce compressor run-time by 20–40% on high-cycle doorways, lowering utility costs and supporting food-safety temperature compliance.
