Question: Can you get installation instructions for concreting?
Document: This mailbox, as sturdy as it appears, actually isn't. It took two grown men to figure out how to get the key, instructions and rest of pedestal out of the mailbox. Even though it was achieved, we also broke the mailbox in turn. After putting the mailbox back together, it wasnt that hard.By the way, it is suggested that you get 80 lbs of cement to pour a slab. It is not like you dig a hole and put the pole in it.
Our last mailbox was vandalized so we decided to get a more substantial one. This is it (so far). It's strong and pretty! Installation is definitely not easy (you need to put it into a concrete pad). But, if you're young enough and know how to do things like that, it's worth it. We are older, so we helped out our local economy by hiring a small construction to assemble and install it.
We followed exact directions for installation. It's a beautiful and solid mailbox. I had read some reviews that said the mailbox would leak in heavy rainfall. We've had several bad storms and the mailbox has remained perfectly tight - no wet mail.This mailbox is very attractive and I love the security feature of using a key to get the mail out.
Check this out! This is a pretty good item, except, the key and instructions are locked inside!!!!! I contacted Amazon.com about this and they said this is common practice for Solar Group. They've gotten many calls about this issue. We tried calling Solar Group directly but their offices are closed. All we could do was laugh at the sheer stupidity. A mulitmillion dollar company actually locks the keys and instructions as a normal practice.
I purchased this mailbox about a month ago and my experience so far has been favorable. Installation took about two hours spread over a couple days. I dug out the base about 8 inches deep, created a simple rectangular form from scrap lumber, and poured a small concrete pad. The next day I installed the assembled mailbox.My only complaint is that there are no reflectors on the mailbox. I bought some reflective tape at the local Home Depot and added a few pieces on the mailbox and post to improve visibility.
Wating for the weather to get warmer to make a change.
This locked mailbox is not only nice looking, but very functional too. I love that it locks and has a huge box for when I can't get my mail right away our when a customer is drooping off pay and I am not her to get it. Highly recommend!
I received this as a gift and it worked well but felt wobbly. When mowing the lawn I tapped it with the lawn mower and the aluminum at the base cracked. Now I have it tied to a tree until I get a better mail box.
always wanted a nice mailbox...always rented then bought a townhouse.well for our newest buy, finally in  a single family, I had to get one.went together well...good finish, nice enough for price.it's not heavy cast iron..it's aluminum.REQUIRES cement...it's very light
Very easy to put together. Less than 20minutes.stylish. love the fact that it has outgoing receptical.Mail is not that secure-open flap & can put ur hand inside the the opening-well at least i can get my mail out without even opening the door.the mailbox i had before was in a car accident!- it was not secure either...
