## Questions & Answers

**Q: Will this work on top of a wooden post?**
A: Yes however an adapter plate might be required for installation. Our compatible 4x4 wood post adapter plate is item # 7540B-10.

**Q: Can it be painted if it fades?**
A: I definitely hope so because after 2 months my beautiful red mailbox is now a     Pepto Bismol PINK. I am planning to paint it red again. It is a great mailbox, looks nice, well made. But it is pink.  I am using a good enamel outdoor paint. But we all know that the sun will cause almost anything to fade after a while. Repaint it and enjoy it. If it fades again, repaint.

**Q: Where can I purchase the 4x4 adapter to mount to my existing wooden post?**
A: Adapter? If you have an existing 4x4 post erected, all you need to do is cut a 1”X 8” 20” long. Nail or screw it to the top of the 4x4 post and screw your mailbox on to the top board (predrilled mounting hole are on the side of the mailbox along the bottom edge

**Q: does this mailbox lock?**
A: No, this mailbox does not have a lock.

## Customer Reviews

### ⭐⭐⭐⭐⭐ You should get this mailbox!
*by S***M on June 19, 2025*

I’m super pleased with this mailbox. It’s larger than a typical mailbox without looking huge. Roomy enough for a few small packages & a pile of mail. The red color is perfect. I specifically bought this so I could tell people “it’s the one with the red mailbox” because our house is easy to miss. And it works great! You wouldn’t believe all the compliments I get for it. It fit right onto the same post I already had for my smaller mailbox. Easy to install. No rust so far after more than 1 year. Still looks brand new. Door works well, no problems. My vinyl stickers stuck really well. Great buy!

### ⭐⭐⭐⭐⭐ Quality mailbox
*by A***! on September 12, 2025*

Good quality mailbox. Color is a true red.Only issue and it's likely due to the postal service tossing the box around the mailbox had a dent in the top of it. Other than that I really like the overall product.

### ⭐⭐⭐⭐⭐ It’s attractive and fun to have an oversized mailbox
*by H***K on January 7, 2025*

I love the style of the oversized mailbox. I don’t have to worry about a mail carrier stuffing mail and other items in the mailbox to destroy it from the post . It’s solid and very durable. It also comes in blue, white , and black.
