The 600 x 450 x 40mm Manhole Cover and Frame B125 Ductile Slide Out Solid Top KD33 is a medium-duty access solution engineered for areas subject to regular vehicular traffic, such as car parks, driveways, pedestrian precincts, and slow-moving commercial yards. Featuring a 600mm by 450mm clear opening and a shallow 40mm frame depth, this solid top unit provides a reliable, low-profile cover for drainage and utility inspection chambers where space or excavation depth is limited.
 
Manufactured from high-grade ductile iron, the cover and frame offer exceptional strength, impact resistance, and durability compared to standard cast iron, while maintaining a lighter profile. Classified as B125 under BS EN 124 standards, it is certified to withstand a test load of 12.5 tonnes (125 kN), making it fully suitable for cars, vans, and light commercial vehicles. The solid top features a slip-resistant textured surface pattern to ensure safe traction for pedestrians and vehicles in wet or dry conditions.
 
Designed for operational efficiency, the slide-out mechanism allows the cover to be easily removed from its frame for routine maintenance and inspection, even in tight spaces. Whether you are installing drainage runs for a residential driveway, a commercial car park perimeter, or a pedestrianized walkway, this trade-quality ductile iron manhole cover delivers certified load-bearing safety, reliable weather resistance, and long-term performance.
