Description
The 610 x 610 x 150mm F900 Ductile Iron Manhole Cover & Frame is part of Wrekin’s Cargo range and is designed for Group 6 installations requiring an F900 access cover. Manufactured from ductile iron, it provides a 610 x 610mm clear opening within a substantial 150mm deep square frame.
Classified F900 Group 6 to BS EN 124-2, the cover is intended for demanding installations where F900 loading is required by the location or project specification. Selection of F900 should be based on the actual loading requirements of the installation rather than simply choosing a higher load classification than necessary.
The Cargo design incorporates enlarged frame corners to distribute loads across the foundation, while an I-beam structure increases rigidity and reduces seat wear. Smooth rounded edges help reduce stress points around the frame, while texturing above and below the flange improves mortar grip and helps reduce lateral movement. Frame holes allow mortar to flow through the flange to create an additional mechanical bond.
For handling and maintenance, the cover incorporates built-in mechanical lifting points, safety keyways designed to prevent accidental lifting-key disengagement and integrated keyway frame lifting points. Wrekin’s GritBlocker system is supplied pre-installed to reduce debris build-up within the keyways and maintain access for future maintenance.
The chequer surface has been independently tested by a UKAS-accredited laboratory to achieve a PSRV value of 70+. The product also complies with CD 534 v0.2.0 and is specified to BS 7903, DMRB and MCHW, alongside its BS EN 124-2 F900 classification and third-party Kitemark certification.
The cover provides a 610 x 610mm clear opening, while the complete frame measures 815 x 815mm overall, with a 635 x 635mm base opening and 150mm frame depth. When replacing existing ironwork, both the clear opening and overall frame dimensions should be checked before ordering, as external frame dimensions can vary between manufacturers and product ranges.
For a larger clear opening within the same Wrekin Cargo F900 range, consider our 685 x 685 x 150mm F900 manhole cover and frame.

What load classification is the 610 x 610 manhole cover?
This manhole cover is classified F900 to BS EN 124-2 and Group 6 under BS EN 124. It should be specified where F900 loading is appropriate for the installation or required by the project specification.
For other sizes at this load classification, view our complete F900 manhole cover range.
What is the clear opening of this F900 manhole cover?
The cover provides a 610 x 610mm clear opening. This refers to the unobstructed opening within the frame and is different from the overall external dimensions of the complete frame.
What are the overall frame dimensions?
The complete frame measures 815 x 815mm overall and has a 150mm frame depth. The manufacturer’s datasheet also specifies a 635 x 635mm base opening.
These dimensions should be checked against the chamber and surrounding installation before ordering.
Can this cover replace an existing 610 x 610 manhole cover?
Potentially, but a matching 610 x 610mm clear opening does not necessarily mean the overall frame dimensions will match. This Wrekin Cargo F900 model has an 815 x 815mm overall frame and a 635 x 635mm base opening.
For replacement projects, check both the clear opening and overall frame dimensions, as these can vary between manufacturers even where the nominal opening size is the same.
Is this 610 x 610 F900 manhole cover CD 534 compliant?
Yes. Wrekin’s datasheet confirms that this product meets the requirements of CD 534 v0.2.0. The product specification also references BS EN 124-2, BS 7903, DMRB and MCHW.
Is this F900 manhole cover Kitemark certified?
Yes. The Wrekin Cargo 610 x 610mm F900 cover is third-party Kitemark certified. The datasheet also confirms its F900 classification to BS EN 124-2.
What lifting and handling features does this cover have?
The cover incorporates built-in mechanical lifting points and safety keyways designed to help prevent accidental disengagement of the lifting keys. The frame also includes integrated keyway lifting points.
Wrekin’s long-handled large-cover lifting keys are available as a compatible accessory.
Is a larger Wrekin Cargo F900 cover available?
Yes. If a larger clear opening is required, DCD also supplies the 685 x 685 x 150mm F900 manhole cover and frame from the Wrekin Cargo range. It provides a larger 685 x 685mm clear opening while retaining the 150mm frame depth and F900 Group 6 classification.
