The CLARK DRAIN CD 60DDI KMC is a hinged ductile iron gully grating and frame designed for reliable drainage in high-traffic areas like kerbsides, pedestrian zones, and car parks. It offers robust C250 load capacity and a secure, captive hinge system. While its durable construction ensures longevity, users should be aware of its specific installation requirements for optimal performance.

C250 classification indicates the gully grate and frame are designed to withstand a test load of 250 kilonewtons (approximately 25 tonnes), making them suitable for use in areas with slow-moving vehicular traffic, such as car parks and pedestrian areas with occasional vehicle access.
The captive hinge system ensures that the grate is permanently attached to the frame via a hinge. This prevents the grate from being accidentally removed and misplaced during maintenance, enhancing safety and security.
The external dimensions of the CLARK DRAIN CD 60DDI KMC are 400mm x 362mm x 75mm. The internal clear opening dimensions are 302mm x 302mm.
No, the C250 classification is suitable for kerbside, pedestrian areas, and car parks. For heavier traffic areas like main roads, a higher classification such as D400 or E600 would be required.
The dished top design helps to channel surface water and debris more effectively towards the drainage opening, improving the efficiency of the gully grate.
It is recommended to inspect the gully grate periodically, especially after periods of heavy rainfall or significant use. A thorough inspection and cleaning should be considered at least annually, or more frequently in harsh environments.
Check concrete bedding for unevenness. Ensure frame is correctly seated and leveled. Adjust bedding if necessary.
Inspect the hinge for trapped debris (dirt, gravel, leaves). Clean thoroughly and apply a suitable lubricant for ductile iron.
Check the grate and the waterway beneath for blockages. Remove any accumulated debris. Ensure the surrounding surface slopes correctly towards the grate.
Cease use immediately. Inspect for structural integrity. Contact the manufacturer or a qualified professional for repair or replacement assessment.
Setup: Proper installation is critical. The frame should be set into concrete bedding at the correct level to ensure flush alignment with the surrounding surface. Ensure the captive hinge mechanism is clear of debris before closing the grate.
Compatibility: This unit is designed for direct installation into C250 rated drainage systems. Its dimensions (External: 400mm x 362mm x 75mm, Internal: 302mm x 302mm) should be matched with the existing or planned aperture.
Care: Regularly inspect the grating and frame for any signs of damage or obstruction. Clean the grate and surrounding area to maintain optimal drainage flow. Periodically check the hinge for free movement and lubricate if necessary, especially in environments prone to corrosion. Use a stiff brush and water for routine cleaning; avoid abrasive cleaners that could damage the ductile iron.
