Why Choose Vandal Stop?
Most competitor boxes, such as those offered by Bradley or Bobrick, use thinner materials and don’t offer dedicated protection against vandalism. Our 12-gauge stainless steel enclosures feature over 2.5x the impact resistance of typical 18-gauge products and are backed by a 10-year vandalism warranty — an industry-first. If damaged due to abuse, we'll repair or replace it.
