Quality mailboxes, personalized customer service, competitive prices, and rapid order turn-around. Security Manufacturing offers a complete line of U.S. Postal Service approved mailboxes including horizontal and vertical apartment mailboxes, locking residential mailboxes, plus multi-styles for the private sectors and universities.

A Company that stands behind It's products.

Since 1979, Security Manufacturing has manufactured mailboxes using the highest quality standards set by the United States Postal Service.  In July 2001, Security Manufacturing was acquired by American Locker Group, Inc. Since 1931, American Locker has researched, designed, and manufactured products using the most advanced engineering techniques in its industry.

Today, Security Manufacturing, with the support of American Locker's engineering group, continues to develop and manufacture the highest quality mailboxes in the industry.  As an international company, mailboxes can be shipped worldwide from our 77,000 sq. ft. manufacturing facility in Grapevine, TX (Dallas-Ft. Worth Metroplex).

All products are warranted in material and workmanship for a period of five (5) years.
