Maintenance Tips

• Clean Surfaces: Wipe thermoplastic door faces and hardware with a soft cloth and mild, non-abrasive cleaner to remove dirt and maintain appearance.

• Inspect Hinges & Pins: Check the Easy Swing® hinge, hinge pins, and bottom pivot pin for wear or looseness; tighten or replace components as needed.

• Check Gaskets: Ensure the full-perimeter gasket seals properly against the frame. Replace if cracked, pulled away, or creating air gaps.

• Monitor Door Alignment: Confirm the door swings smoothly and closes flush without rubbing or catching. Adjust frame or hinge alignment if needed.

• Maintain Impact Protection: Inspect bumpers, impact plates, or guards for damage; secure or replace as needed if the door is exposed to carts or pallet traffic.

• Prevent Corrosion: Keep all exposed metal surfaces dry and free of rust or coating damage, especially in refrigerated or humid areas.

• Seasonal Check-Up: At least twice per year, inspect fasteners, clean frames, and lubricate moving parts to maximize longevity.
