Description
The Allegro Safety 9406‑36A Adjustable Large Manhole Safety Cross is a durable manhole safety device engineered to protect workers and passersby by limiting access to danger zones around large manhole openings. This two-bar system interlocks at the center to significantly reduce the effective opening size, helping to minimize the risk of falls into confined spaces — a common hazard on utility, municipal, and construction sites.
