Setup, Compatibility & Care
To install this unit, you must first measure your door thickness to ensure it does not exceed 1.7 inches. Carefully mark the dimensions required for the slot on your door, ensuring it is level. After cutting the opening, insert the drop box and secure it according to your door material. Regular maintenance involves wiping down the exterior with a damp cloth to remove salt or grit that might degrade the finish. If the combination lock feels stiff, you may apply a small amount of dry graphite lubricant to the mechanism. Periodically inspect the drainage holes at the bottom to ensure they remain clear of debris to maintain optimal moisture protection.
