Resintuff 700mm x 700mm Triangular Manhole Cover, 25 Ton Rating

Resintuff Triangular Manhole Cover

The Resintuff 25 Ton Manhole cover provides a high-strength access solution for subsurface drainage and utility networks. This composite unit utilizes fiber-reinforced materials to achieve a C250 load rating. It fits standard 700mm x 700mm openings in residential and commercial environments.

Built for the Job

Civil contractors and plumbers specify this access unit for areas requiring medium-duty load bearing. The triangular configuration is a safety feature that prevents the lid from accidentally falling through the frame into the shaft during maintenance. Unlike traditional cast iron, the composite material offers no scrap value. This significantly reduces the risk of theft on public sites. The lightweight nature of the resin-based material allows for safer handling by site crews without specialized lifting machinery. It resists corrosive sewer gases and chemicals found in industrial runoff.

• Installation in residential driveways and private car parking areas.

• Access points for municipal sewerage and stormwater drainage systems.

• Utility pits for telecommunications and electrical cabling.

On-Site & Workshop Notes

• Ensure the frame sits on a level, full bed of high-strength mortar to prevent rocking.

• Check the orientation of the triangular lid during installation to ensure correct seating in the frame grooves.

• This medium-duty unit is not suitable for high-speed carriageways or heavy industrial loading areas.

• Clean the seating flange before final placement to ensure a flush fit and minimize noise during traffic transit.
