The most effective method of proactively protecting workers from falls is to eliminate the fall hazard and one of the most effective solutions for eliminating the hazard is with FallTech's portable construction guardrail assembly. The dual-application guardrail assembly is adjustable for parapet wall and slab edge thicknesses from 61/2 in to 241/2 in and installs easily with common user-supplied 2 x 4 dimensional lumber. Each assembly features rail brackets for top and mid-rail guards and for toe-boards when used on slab edges. FallTech temporary construction guardrails are highly portable and provide a cost-effective solution for common construction hazards like wall and floor openings, uncovered holes, roof and elevator openings and unprotected ramps and leading edges.
