NEED HELP PLEASE
Help please. I ordered the unit last week and the tall portion delivered today 3/26/23. The mail box holder and plant box to be mailed shortly. No instructions with the tall portion so have a question. If it takes a 4X4X8 with about 3 feet in the ground and 5 feet (60 in) left for the unit to sit over wood, I notice that the plastic tall portion can only take 23 inches of the 4x4 since there are portrusions in side that stop it from going to the full 56 inches to the top. Advise please. Thanks.
Hi Murray, Thanks for the review! There is room on the inside of the post sleeve to accommodate a standard pressure treated 4x4 wood post (actual measurement of these posts is 3.5"x3.5"). Full installation instructions as well as instructional videos can be found on our website at gomayne.com.

Good after digging new hole for post.
Very nice mailbox. We did have to start new with post because after you place the mailbox it would have been too far out in road. Not a simple switch out. Also shop because other places has it 30 bucks cheaper.
