The standard rear-loading Guardian system is a secure, economical alternative to standard aluminum mailboxes. Each door comes standard with a new bent cam to prevent the doors from being pried open. Mailbox housing is made of 24-gauge durable galvanneal steel.
The standard Guardian system is designed to be stacked 2 units high, mounted side by side, or between standard wall studs. All units have identical outside dimensions, allowing you to mix & match different door sizes. The Guardian is ideal for universities, military installations, and anyplace needing a private mail system.
