Mailbox and 6x6 In Ground Post · Mailboxes & Posts
Installing the In-ground Post
1Watch our "Preparing Your Post for Installation" video.
2Time to dig! Check for utility lines first. You need a hole about 12" in diameter and 16" deep for the 6x6 post. Note the "front" directional sticker on the post and orient accordingly.
3Add ½ a bag of quick setting concrete to a few inches below top of hole.
4Add water! You want it to hold the post but still be moveable — like a concrete smoothie. (Stir a bit.)
5Check final orientation height, and for level in both directions.
6Cap off the hole with extra dirt, packing down as you go. Check level as you tamp.
7Check level one last time and let concrete cure for an hour or so. Wash off any concrete residue.
