Operating Instructions
The Qualarc Kingsbury Mailbox is designed for simple and secure operation.
Mail Delivery
- Locate the incoming mail slot on the front of the mailbox. The incoming opening dimensions are 9"W x 2.5"H.
- Gently lift the mail flap.
- Insert mail into the slot. The design ensures mail drops into the secure inner compartment.
- Release the mail flap to close the opening.
Mail Retrieval
- Access the rear of the mailbox where the lockable access door is located.
- Insert one of the two supplied keys into the lock.
- Turn the key to unlock the door.

- Close the door firmly and turn the key to lock it. Remove the key.
Maintenance
To ensure the longevity and appearance of your Qualarc Kingsbury Mailbox, follow these simple maintenance guidelines:
- Cleaning: Periodically wipe down the exterior surfaces with a soft, damp cloth. For stubborn dirt, a mild soap solution can be used. Avoid abrasive cleaners or harsh chemicals, as these may damage the enamel finish.
- Lubrication: If the lock mechanism becomes stiff, apply a small amount of graphite lubricant or a silicone-based spray to the keyhole. Do not use oil-based lubricants as they can attract dirt.
- Inspection: Regularly inspect the rubber seals around the castings for any signs of wear or damage to maintain waterproofing. Check the integrity of the mounting points.
- Key Care: Keep spare keys in a safe, accessible location. Avoid forcing the key if it does not turn easily.
Troubleshooting
This section addresses common issues you might encounter with your mailbox.
Issue: Mailbox door is stiff or difficult to open/close.
Solution: The lock mechanism or hinges may require lubrication. Apply a small amount of graphite lubricant or silicone spray to the keyhole and hinge points. Ensure no debris is obstructing the door's movement.
Issue: Water inside the mailbox.
Solution: Although designed to be waterproof, check the rubber seals around the castings for any damage or displacement. Ensure the mail flap closes completely after mail delivery. Verify that the installation was done correctly, preventing water ingress from the mounting surface.
Issue: Key is difficult to insert or turn.
Solution: Ensure the key is fully inserted. Apply graphite lubricant to the keyhole. If the key is bent or damaged, use a spare key. Do not force a damaged key, as it may break inside the lock.
