Description
The Allegro 9406-24A Adjustable Small Manhole Safety Cross is a robust, steel manhole safety device engineered to limit access to dangerous openings in roadways and work zones. Featuring an adjustable cross-bar design, this unit fits a range of smaller manhole diameters (18″, 20″, 22″, and 24″) without tools, helping crews quickly secure openings before work begins. Its two-bar system interlocks at the center, effectively reducing the hazard area and minimizing the risk of falls into the hole — a key safety measure for crews working around sewer lines, utility vaults, and confined spaces.
