              Can this mailbox unit be attached to wall? Can't do concrete pad to to main water lines.
              ByJul 29, 2024
              1 Answer | 
              Answer This Question

              This mailbox and pedestal unit is designed for post mounting and doesn't have the necessary features for direct wall mounting. While some smaller mailbox units offer wall-mounting options, this particular model is USPS-approved specifically for post installation. You would need to consult your local postmaster for approval if you wish to modify the installation method. A surface wall-mounted unit like the Salsbury Industries 4C Horizontal Mailbox might be a more suitable alternative for your situation.

                The product was delivered damaged and Sasbury Industries would not do anything about it. Home Depot was great and played the middle man between me and the manufacture. The product was ok the customer service (Sasbury Industries) was the terrible. I will continue shopping at Home Depot but will not buy any of Sasbury industries products.
