Marshalls Civils & Drainage has introduced a purpose-built manhole safety cover to address the safety risks of exposed manhole shafts during construction. Designed to fit all standard cover slab access holes, it offers a durable, reusable, and highly visible solution that supports pedestrian loads up to 500kg. With multiple sizes, locking features, and corrosion resistance, it provides a reliable and secure alternative to makeshift or inadequate covers - or often, the lack of any safety measure at all.
