FAQs
What is the load rating C250?
A C250 load rating indicates the grate and frame can safely withstand a test load of 250 kilonewtons, suitable for areas subjected to medium traffic loads like car parks and driveways.
How is the clear opening size measured?
Manhole covers and grates are measured by the clear opening size they are intended to cover, not the overall dimensions of the frame.
Can this grate be used in areas with heavy truck traffic?
No, the C250 rating is not sufficient for heavy-duty traffic such as that found on main roads or industrial sites. Consult product specifications for higher load-rated options.
What material is the CD60 DDI KMC made from?
It is constructed from durable ductile iron, known for its strength and resistance to corrosion.
Is installation difficult?
Installation involves proper groundwork and seating the frame securely. While straightforward, it requires attention to detail to ensure safety and performance. Professional installation is recommended for critical applications.
How do I maintain the hinged mechanism?
Periodically clean the hinge of debris and ensure it moves freely. Lubrication may be beneficial in environments prone to rust or corrosion.
What are the overall dimensions of the product?
The overall frame size is 400mm x 362mm, while the clear opening is 302mm x 302mm.
Troubleshooting
Grate does not sit flush
Check for debris or unevenness in the frame seating or surrounding surface. Re-level the frame if necessary.
Hinge is stiff or difficult to operate
Clean any dirt or grit from the hinge mechanism. Apply a suitable lubricant if necessary.
Water pooling around the grate
Ensure the gully grate and drainage pipe are clear of blockages. Clean out any debris that may be impeding water flow.
Signs of premature wear or damage
Inspect for impact damage or exceeding the C250 load rating. Contact the manufacturer if significant damage is observed.
Pros and Cons

Setup, Compatibility & Care
Setup:
Ensure the surrounding groundwork is prepared according to standard construction practices for drainage installations.
Position the frame within the prepared opening, ensuring it is level and securely seated.
The grate, being hinged, can be swung open for access and closed securely.
Compatibility:
This unit is designed to cover clear openings of 302mm x 302mm. Always measure the intended opening to confirm compatibility.
The C250 rating means it is suitable for applications where the maximum test load does not exceed 250 kN (approximately 25 tonnes).
Care:
Periodically inspect the grate and frame for any signs of damage or obstruction.
Ensure the hinge mechanism is free from debris and operates smoothly. Lubrication may be required in harsh environments.
Clean any accumulated debris from the grate to maintain optimal drainage flow.
Avoid using abrasive cleaning agents that could damage the surface finish.
