Curtron PP-C-120-3678 Polar-Pro Flexible Swinging Walk-In Door 36"W x 78"H - CUPPC1203678

Polar-Pro Flexible Swinging Door for Walk-In Coolers & Freezers, 36” wide x 78” high, (2) .120” thick clear PVC panels (rated for -20° to 140°F), (2) stainless steel swinging arms and universal mounting brackets, and (2) anti-curl strips.

What our Experts Think

• Compact Full-Height Access (36″ × 78″) — Perfect for walk-in cooler or freezer entrances where width is limited but full height is needed.

• Flexible PVC Panels — .120″ clear PVC remains durable and flexible down to –20 °F, reducing cold-air loss and maintaining environment control.

• Smooth Swing Operation — Stainless-steel swing arms and anti-curl strips ensure panels open and close flush, maintaining proper sealing.

• Durable & Easy to Install — Universal mounting brackets resist corrosion and support both in-jamb or face-of-wall installation.

• Energy & Workflow Efficiency — Allows main walk-in doors to stay open while the swing door maintains the thermal barrier, reducing compressor load.

Q&A

Q1: What size opening is this door designed for?
A1: Fits a 36" wide × 78" high doorway, ideal for smaller personnel or service-access walk-ins.

Q2: What material and temperature range does it support?
A2: Flexible Polar-grade PVC panels (.120" thick), suitable for temperatures from –20°F up to 140°F.

Q3: How is the swinging mechanism different from a traditional strip door?
A3: Torsion-spring swinging panels ensure smooth motion, full closure, and effective sealing compared to hanging strip or gravity-hinge doors.

Q4: What durability and installation features does it have?
A4:

• Stainless steel universal mounting hardware for long-lasting corrosion resistance

• Anti-curl strips on each panel maintain proper alignment and seal

• Can be mounted in-jamb or surface-mounted on the wall for flexible installation

Q5: How does this door improve energy efficiency and workflow?
A5: Maintains temperature inside the walk-in while allowing frequent traffic, reducing warm air intrusion and refrigeration energy use.

Q6: Where is this door commonly used?
A6: Ideal for walk-in coolers or freezers in restaurants, supermarkets, and cold-storage facilities requiring moderate traffic and strict temperature control.

Maintenance Tips

• Clean the PVC panels regularly: Use a soft cloth with mild dish soap and warm water; rinse and dry thoroughly. Avoid spray solvents, acetones or abrasive cleaners.

• Inspect hinge arms and mounting hardware every 3–6 months: Check for loosened fasteners, corrosion, or wear; tighten hardware and ensure the stainless‑steel arms are secure.

• Check panel alignment and overlap quarterly: Both panels should return to a sealed position without gaps; if not, adjust spring tension or bracket alignment.

• Keep swing path clear of obstacles: Ensure carts, debris or buildup do not interfere with the panel movement or mounting brackets.

• Replace damaged PVC panels or anti‑curl strips promptly: Any cracks, warping or curling reduce sealing performance and energy efficiency.

• Avoid harsh cleaning methods: Preserve the flexible PVC by using non‑abrasive tools and mild cleaning solutions only.
