When ACORN Wire and Iron Works began in 1913, brothers Frank and Herman Kitzelman originally manufactured mesh guards that wrapped around trees to prevent horses from eating the bank. Mesh window guards were soon added to the company's product line.

As the company grew, and the need for horse-proof mesh decreased, they moved to their 4940 S. Kilbourn Ave., Chicago, facility. During the post-WWII boom, the family business branched out into other manufacturing venues, such as security folding gates for schools and wire mesh partitions for access control. It was also during this time that ACORN began focusing more heavily on the quality aspects of their products by creating lighter and easier-to-install security gates and partitions that incorporated solid riveting and higher quality casters and rollers. ACORN Wire and Iron Works set the standards for security folding gate and wire mesh manufacturing - and continued to exceed those standards.

Eventually, the company's management succeeded to Robert Stitt, Frank's grandson. Now with Mr. Stitt's guidance, ACORN enters ito its next generation of production and customer service. Ever adapting and evolving, ACORN's product applications have grown - and continue to grow. Today ACORN is a leading manufacturer of security gates and wire mesh partitions. ACORN has solutions for many applications including school safety and homeland security, as well as protection against loss and vandalism.
