OSHA requires that employers provide fall protection as stated in Regulation 29 CFR 1910.23 (Guarding Floor and Wall Openings and Holes), and Regulation 29 CFR 1926.501 (Duty to Have Fall Protection). Skylight screens are easy-to-install aftermarket fall protection devices designed to meet these OSHA regulations. The guardrail and screen style fall protection systems do not penetrate the roof or skylight curb membranes, thereby maintaining the integrity of the roof warranty. The standard guardrail is electro-galvanized steel tube. Stainless and aluminum tube are also available if specific corrosive applications require their use. The standard skylight screen is made from 304 SS wire mesh with stainless steel hardware. Hot dipped galvanized mesh is also available.
