Key•stone n. the wedge shaped piece at the summit of an arch.

Gaines Manufacturing is proud to manufacture the finest mailboxes in the world. The "Keystone Series" is die cast from the highest quality A-360 rust-proof aluminum with optional solid brass accents. Each model is finished with a durable state of the art five-step powder-coat paint process. The two distinctively different front door designs were carefully thought out to complement the architecture of almost any home. Keystone Mailboxes are a blend of traditional style and contemporary good looks. Note the difference in the styles by the sides of the door and the keystone design at the top. Door A has a block design and Door B has a column look. The keystones are designed to compliment the side ornamentation.
Door "A"   Door "B"
The design team at Gaines Manufacturing thoughtfully designed the bottom plate of each mailbox to accept a wood 4x4 post with incredible ease if you choose to install your mailbox in that fashion. To install simply use a 3/8" wood screw to mount your mailbox directly on top of a wood 4x4 post or utilize their matching Mailbox Posts.

With the flag detached the "Keystone Series" mailbox can be built into a pilaster for that extra special installation.
