750 x 600mm Ductile Iron Manhole Cover and Frame B125

This 750 x 600mm ductile iron manhole cover and frame is a solid top B125 rated access cover designed for external chambers in domestic and light commercial settings. It is a common choice for private driveways, parking bays, paved service areas, pedestrian routes and utility access points where a recessed finish is not required.

The solid top lid remains visible once installed, giving direct access to the chamber below without lifting paving blocks, slabs or surrounding finishes. For many customers this is the better option where practicality, strength and routine access matter more than appearance.

Manufactured from spheroidal graphite ductile iron, the CD 722 KMB offers stronger impact resistance and improved structural performance compared with older grey cast iron covers. When correctly installed on a full concrete or mortar bed, it provides dependable service under repeated car and light van traffic.

The 750 x 600mm clear opening gives useful working space for larger inspection chambers, drainage runs and utility connections. This size is often selected where 600 x 450mm covers feel restrictive for maintenance access or where chamber dimensions already suit a larger frame.

Integral lifting key holes are built into the cover, allowing controlled removal with compatible keys. The slide out lid design also helps reduce awkward lifting movement during access, which is useful where covers are opened for periodic inspection.

B125 loading is intended for BS EN 124 Group 2 locations such as driveways, private parking areas and pedestrian zones with occasional vehicle use. It should not be specified for highways, delivery yards with regular HGV traffic or adopted roads where D400 or above is normally required.

If replacing an existing cover, always match by clear opening size first, then confirm overall frame dimensions and bedding depth before ordering.
