Why Choose Vandal Stop?
Competitor models, such as those from Bobrick or Bradley, often use 16- or 18-gauge steel and offer limited warranties. Vandal Stop enclosures feature true 12-gauge construction and the only 10-year vandalism warranty in the industry. When security, longevity, and reliability matter — Vandal Stop leads the way.
