The Mail Manager is constructed of 14-Gauge and 16-Gauge galvanized steel and features the same patented anti-pry latch locking mechanism as our larger curbside models. The Mail Manager is our best selling locking mailbox - for all the right reasons. The upper, incoming mail door allows for delivery of small packages and awkward shaped items such as prescription mailers, legal sized envelopes and other small packages - all without compromising mail security. The Mail Manager features a bin style incoming mail door that can accommodate packages up to approximately 3.5 in. x 3.5 in. x 10.5 in. Additionally, legal sized envelopes up to 10.75 in. W and Outgoing mail, such letters or small envelopes can be placed into a spring metal clip behind the upper, unlocked door. The lower, locking, mail retrieval door is extremely rigid and durable. Secured by our patented, hook-and-pin cam and welded anti-pry bar, the Mail Manager curbside mailbox is the ultimate security and value for residential users. Color: Marigold.
