Just so you know, this mailbox unit does NOT come with a lock. You have to get one separately. But the mail slots are a good size, it's a nice, sturdy unit.Item arrived damaged, not the fault of shipping carrier but because of manufacture’s poor and cheap way of boxing the item.The postal agent install the keys and everything went well as expected.Love the Mailbox, wish they would have a outdoors line that's weather-proof. My mail tends to get a little damp after a good rainstorm.BTW obtaining a master latch from the USPS is a PAIN in the A**... may want to keep that in mind. They should offer a universal latch assembly for purchase so we can just give the key to the postal carrier as an option in the meanwhile.Easy installation. Very sturdy. Good size.Beautiful and perfect for us though I initially was looking for one with only two slots. Looks the same as the picture, was easy to put up. Simply had to have the post office add their own lock. Our mailman even complimented us on the new box. We've had it for a year (albeit under a covered porch) and it looks as good as the day we purchased it.Installed in a condo project I’m working on and they look great!This was second one I bought, first for another location was 7 years ago and it still looks new and zero maintenance.
