ACRO Building Systems shares our top priority, which is always worker safety. Since their establishment in 1992, ACRO has focused on innovation in alternative fall protection to not only align with updating and changing OSHA regulations but to ensure safe working conditions. In 1995, they invented the 19-inch contractor bracket which quickly led to the development of the Residential Guardrail System, “Roof Bracket with a Post.” For the next 20 years, they continued to work to develop newer, safer products and continue that mission today.
