Our 700 × 500 mm rectangular manhole cover is certified to BS EN 124:2015 Class D400, designed to resist 400 kN (40 tonne) static loads for carriageways, hard shoulders, parking areas, and block paving installations. The clear opening precisely measures 700 × 500 mm, fitting standard rectangular inspection chambers, while the robust frame stands 100 mm tall to accommodate paving depths and ensure flush, stable seating. Manufactured from high‑grade GGG500‑7 ductile iron for exceptional strength and ductility, the frame is finished in cold‑applied bitumen for corrosion resistance (optional epoxy powder‑coat available). A reversible brick‑support flange allows seamless block‑paving recessing, matching surfacing profiles without additional trimming. Part of EJ’s proven D400 rectangular cover range, it integrates effortlessly with existing frame systems and is stocked by leading suppliers like Drainage Superstore for rapid delivery worldwide.
