Garlock Safety Systems’ Crossover Stairs provide a safe, modular solution for navigating over pipes, ducts, conveyors, or other rooftop and facility obstacles. Designed with OSHA compliance in mind, this system includes 36” square work platforms, high-traction stair treads, and a continuous handrail to ensure maximum safety for personnel. The heavy-duty galvanized steel construction offers long-term durability and corrosion resistance, making it ideal for both indoor and outdoor environments.
