FAQs

Can I use this cover on my driveway?

No. This cover is rated A15, which is intended strictly for pedestrian traffic. It will likely fail under the weight of a vehicle.

What is the diameter of the opening?

The cover is designed for a 450mm diameter inspection chamber.

Is this cover weather-proof?

It is designed for outdoor use and will prevent surface debris from entering the drainage system, though it is not hermetically sealed against high-pressure water.

What standards does this product meet?

It is manufactured to BS 5834 standards and conforms to EN124 requirements.

How deep is the installation frame?

The frame depth is 30mm.

Troubleshooting

Cover feels unstable or rocks when walked upon

Ensure the frame is bedded correctly into a mortar or concrete base to achieve a solid, level foundation.

Hinge is stiff or difficult to open

Clear any accumulated dirt, grit, or debris from the hinge mechanism and apply a light silicone-based lubricant if necessary.

Pros and Cons

Pros

Hinged design simplifies routine inspection and cleaning
Certified to BS 5834 and EN124 industry standards
Perfect fit for standard 450mm circular chambers
Durable construction suitable for outdoor domestic use

Cons

Not suitable for driveways or areas with vehicle traffic
Limited to pedestrian-only zones
Requires proper bedding for stability

Setup, Compatibility & Care

Installation requires a level, stable base. Ensure the surrounding material is properly compacted so the 30mm frame sits flush without rocking. Compatibility is restricted to 450mm diameter chambers; verify the existing chamber rim matches these dimensions before installation. Maintenance is minimal: keep the hinge free of debris to ensure smooth operation, and occasionally clear the gap between the cover and frame to prevent the build-up of silt or grit that might make opening difficult over time.
