Our 550 mm drop‑in manhole cover complies with the latest BS EN 124:2015 standard for gully tops and access covers in vehicular and pedestrian areas. Rated as B125, it is engineered to withstand a 125 kN (12.5‑tonne) test load, making it perfect for footways, pedestrian zones, and light vehicular areas such as car parks. The clear opening diameter measures 550 mm, set in a robust 670 mm × 670 mm square frame that is 60 mm deep to ensure strength and stability.
