Troubleshooting

Setup, Compatibility & Care

Installation is straightforward due to the pre-drilled holes on the back of the unit. First, choose a flat, vertical surface that is accessible to postal carriers. Align the unit and use the provided mounting kit to secure it to your wall, shed, or garage. For brick or concrete walls, you may need a masonry drill bit to create the initial pilot holes.

To keep your post box in peak condition, wipe the exterior with a damp, non-abrasive cloth periodically to remove dust or salt buildup. Avoid using harsh chemical cleaners, as these may damage the corrosion-resistant finish. Lubricating the lock mechanism with a silicone-based spray once or twice a year will ensure the keys turn smoothly and prevent sticking during winter months.
