Question: Does it have a lock?
Document: Our gardener backed into our mailbox so we needed to replace it. I wanted black but could not find one at a good price anywhere. We hired someone to paint this one black which is okay but some of the white plaint is showing through at the bottom. I also find the lock very cheaply made.
I chose nuts that the supplied white plastic caps fit over. I also made a template of cardboard. The 2 bolts that secure the post to the base leaves something to be desired. Also there is no red flag to signal the Mailman of outgoing mail, but not a problem since there's a box 100 ft from my house. The lock with 2 keys is a plus if you're out of town for any period of time. It is the nicest mailbox on the block as I'm told on a regular basis.
Well worth the price! Easy to install and looks great in fron of the house. Would recommend and would purchase again if necessary!
UPDATE 06/18/12 - Slightly more than 1 years after posting this review on this mailbox, I have some additional information to share:-I discovered that the actual brand-name of this product is "Amco".-It has held up well. The aluminum has not decayed and is of course not going to rust. The steel bolts used to construct it have not rusted either, but I attribute that to the several layers of caulking I applied to every possible crevice when I first built it.
To repair it, I had to place a steel rebar down the stem and filled it with concrete. It is still standing after almost a year since its last encounter with a black Ford Mustang.
Though I was able to work around the product's limitations, here is a list of things that did not impress me about my purchase:-No outgoing mail section, only incoming.-Since there is no outgoing mail, it of course does not come with an outgoing mail indicator.-Came with too many of some parts, not enough of others (2 missing screws, 5 too many washers, 3 missing screw caps).-NOT gasketed and NOT water-resistant. Your mail WILL get wet.
Those units have their issues also, but reviews indicate that manufacturer is at least making improvements to their product. Spend the extra money and get that unit instead, otherwise be prepared to spend more on gas, caulking, and time to make this unit usable. I give this unit 2 stars because it arrived quickly, was undamaged and was priced cheaply, NOT because I would recommend its quality (or lack thereof).
This product was more than what I expected. I am very satisfied with it. I would defenitely order this item again
This mail box is stylish and well made. It was easy to assemble and install. I think it was a good bargain for the money. I did caulk it on the inside to seal spaces between the parts to ensure that rain water would not get in.
This item is sturdy and arrived in a short time. It dosn't open from the front or have a flag for mail pick up. Would have liked thes features.
Answer: yes
