    Install without concrete, use a gravel and dirt mix make sure you install per USPS guidelines and plumb to the center line of the road. Also bring help a real and proper granite mbox post can weigh in excess of 300 pounds.

    I believe the USPS requires mailbox poss to be "collapsible"

    We don't use concrete. We back fill around it with 3/4" processed gravel. Compact the gravel with a sledge hammer (use the top of it).

    DVS, anything is collapsible with a big enough hammer :laugh:
