Use Acro's proven Steep-pitch Guardrail Brackets along the eave-edges from 4/12 to 16/12. Two sets of 2 x 4's are used with a toe board to form a continuous guardrail around the entire roof edge. This innovative full guardrail system is easy to install, move & remove without damaging shingles on any roof 16/12 pitch and under. This allows the guardrails to be put up early in the new construction process or even prior to shingle removal on a tear off and easily moved without having to take the system down. Acro now offers a way to comply fully with OSHA's 2011 requirements without the need of any other impeding safety equipment.
