Question: Will 4-inch address numbers fit on the Solar Group GC1B0000 Large Deluxe Plastic Mailbox and Post Combo?
Document: My former mailbox was rusted and the wooden post damaged by water from the sprinkler. My mail was often wet. I simply cut off the rusted-out mailbox along with the top portion of the post and slipped the plastic mailbox and post combo right over it, then attached it with the screws that came with it and viola! An easy fix and no more wet mail!
Purchased for a rural route business mailbox. Very solid and good looking! It should last for a very long time! Highly recommend it for business or residential use. The only thing that would be helpful to add is a set of numbers to attach for the address.
This mail box is great, it is sturdy, well built and convenient to use. The mail man thinks it great because it is large enough to fit a lot of packages. Our neighbors think  it looks great. We are very happy with our new mailbox and look forward to many years of use. My husband had no problem installing it or putting it together.
Even more amazing it was all in one piece with absolutely no damage to it. It was one of the few mailboxes still standing and in one piece in the whole aria.This is a one piece double walled mailbox, the post and the box are molded together. The post has a 4 by 4 in cut out section where a wood post can be inserted. It has a pull open door in front and another one in back.
This looks much better than the other plastic mailboxes. Big improvement from our old and tired mailbox and wooden post. So easy to put together and install and it is very sturdy. Also, the newspaper slot is nice to have.
Best to prop it up with something while the cement is drying "After the cement is dry and the wood pole is set, place the mailbox and it's post over the wood post. When its in it's proper position take the large wood bolts and screw them in attaching the mail box post section to your cemented in wood post.That should do it.
This mailbox was very difficult to assemble by oneself. The very first piece to be attached to the bottom would not fit properly. It didn't match-up exactly as it should have. After the box was assembled and the sleeve was attached to the post, it required two people to slide the box onto the base. The back door of the mail box will not stay shut during windy weather. When the mail carrier opens the front door the back one opens. It is not tight enough.
The newspaper slot below always stays dry even on the wettest days. Easy to install over a 4&#34; by 4&#34; post set in concrete, it looks great and will last for many years.
Went together easily and fit over my existing 4x4 post that had a damaged #10 Box affixed. Box portion does not seem overly solid as is affixed to the post by a single screw, but time will tell. Does look pretty good and am planning to decorate with a vinal wrap and a metal street number.Note that this is a Rubbermaid Gentry mailbox you can pick up loaclly at Home Depot for about the same price. It even came in a Rubbermaid box.
I was pleasantly surprised to find out that this mailbox is not only very roomy but strong too! It took me around 7 minutes to put together the mailbox with the help of an electric drill, and about 3 minutes to attach it to an existing post. I am not very mechanically inclined so this item truly is easy to assemble. Directions are clear and concise. The mailbox is very large and even the attached flag is thick and sturdy.
