What our Experts Think
-
Space-Efficient Access: Flexible swinging door measuring 42″ wide × 78″ high, ideal for walk-in coolers/freezers with limited space or lower-height openings.
-
Temperature-Rated PVC Panels: Dual clear PVC panels (~0.120″ thick) suitable for temperatures from ‑20 °F to 140 °F, providing durability in cold-storage environments.
-
Smooth Operation: Includes swing arms, mounting brackets, and anti-curl strips for reliable, easy movement while maintaining internal temperatures.
-
Energy & Workflow Benefits: Flexible swinging design minimizes air exchange, supporting thermal efficiency and reducing refrigeration load.
-
Mid-Traffic Ready: Well-suited for walk-in units with frequent staff or cart movement, but not designed for heavy industrial traffic.
-
Installation Considerations: Ensure wall framing, header clearance, and swing radius accommodate the door’s design and that the 78″ height fits your opening.

Q: What should an installer check prior to ordering?
A: Confirm the opening is 42″ W × 78″ H, ensure the mounting surface supports hardware, allow full panel swing clearance, and maintain proper floor clearance to prevent buckling.
Q: Why choose this model instead of a rigid door?
A: Allows free two‑way traffic flow, reduces temperature loss, minimizes condensation build‑up, and offers a flexible, cost‑effective solution for refrigerated environments.
Maintenance Tips
-
Clean PVC Panels: Wipe the clear PVC panels regularly with a soft cloth and mild, non-abrasive detergent to maintain visibility and prevent buildup.
-
Inspect Hardware: Check stainless-steel swinging arms and mounting brackets for looseness, corrosion, or wear; tighten or replace as needed.
-
Check Panel Alignment: Ensure the two swinging panels overlap correctly. Adjust the alignment plate if panels do not close flush.
-
Adjust Spring Tension: If panels do not return fully to the closed position, adjust the tension screw on the bottom bracket.
-
Maintain Bottom Clearance: Ensure panels are about 1/8" above the floor. Inspect no-curl strips at the bottom and replace if damaged.
-
Verify Proper Sealing: Confirm panels maintain a tight overlap to preserve temperature control and energy efficiency.
