Keystone Mailbox Lockable Insert
Turn any Keystone Mailbox into a lockable one with this Lockable Insert. It also comes with two keys for extra added security. With a Keystone Mailbox Lockable Insert, you are surely protected against mail and identity theft.

Metal and Finish
The Keystone Mailbox Lockable Insert is constructed from durable A360 rust-proof cast aluminum. Extremely sturdy and light-weight at the same time, cast aluminum is 100% rust-resistant. It is formed by pouring aluminum into a mold of the end product. During the manufacturing process, the aluminum goes under substantial amounts of pressure, which produces an extremely dense material that can withstand the harshest of conditions.

A five-stage, powder-coated paint process is utilized to ensure that the Keystone Mailbox Lockable Insert is quality-wise consistent, durable, and possess a high-quality finish. Powder coating has ultraviolet ray (UV) inhibitors that protect the surfaces, making the finish resistant to chipping, scratching, fading, and wearing. Color remains bright and vibrant for the longest time. The Keystone Mailbox Lockable Insert is available in an elegant black finish.
