I love this mailbox! I’m especially excited about never having to paint my mailbox post again! The post is plenty long and sturdy enough to concrete directly into the ground, but we already had an old mailbox post, so we cut the original post off below the arm, cut down the bottom of the new PVC post, and slipped it right over it. The bottom detail piece is separate and can slide up the post, so we screwed the PVC post to the 4x4 original wood post underneath. Then we slid the bottom detail piece down over it, and bam! Looks great. Only thing I’m disappointed about is I thought I’d get stickers for the sign underneath but I didn’t. There was also a small dent in the top of the mailbox itself, but it’s barely noticeable.
