Description
The DU112 600 x 450 x 70mm C250 Double Seal Ductile Iron Manhole Cover is a premium access cover designed for commercial and light traffic environments where a higher level of sealing performance is required. Manufactured from high-strength spheroidal graphite ductile iron, it combines the durability of a traditional C250 cover with the added benefits of a double rubber sealing system, helping to reduce odour escape, minimise surface water ingress and provide quieter in-service performance.
Certified to BS EN124-2:2015 and carrying the BSI Kitemark, the DU112 is suitable for Group 3 installations, including kerbside locations extending up to 500mm into the carriageway, commercial premises, business parks, service yards and car parks. The integrated SmartGrip® anti-slip surface provides excellent skid resistance in both wet and dry conditions, making it a dependable choice for areas regularly accessed by cars and light commercial vehicles.
Unlike standard solid top covers, the DU112 belongs to the EasySeal range, offering enhanced sealing performance for projects where odour control, reduced water ingress or quieter operation are important considerations. This makes it particularly well suited to foul drainage chambers, utility infrastructure and service ducts located close to occupied buildings or public spaces.
With a 600 x 450mm clear opening, 710 x 560mm overall frame and 70mm frame depth, the DU112 offers straightforward installation into new and existing chamber constructions. Optional locking, venting and badging are also available for projects requiring additional security or bespoke specifications.
Whether you’re specifying drainage infrastructure for a commercial development, replacing an existing access cover or sourcing products for a highways or civil engineering project, the DU112 delivers the strength, reliability and sealing performance expected from the Eccles EasySeal range.

What makes the DU112 different from the DU023?
Both covers share the same 600 × 450mm clear opening, 70mm frame depth and C250 load rating, but the DU112 incorporates a double rubber sealing system, making it better suited to applications where improved odour control, reduced water ingress and quieter operation are required.
What are the benefits of a double seal?
A double seal helps:
- Reduce unpleasant odours escaping from below ground.
- Limit rainwater entering the chamber.
- Reduce cover movement and rattling.
- Improve long-term performance.
Is this suitable for foul drainage chambers?
Yes. The double sealing system makes the DU112 an excellent choice for foul drainage and sewer applications where a tighter seal is desirable.
Can this cover be locked?
Yes. Locking options are available where additional security is required.
Is this cover suitable for highways?
The DU112 is designed for C250 Group 3 loading, making it suitable for kerbside locations, commercial vehicle areas and similar applications. For main carriageways carrying continuous heavy traffic, a D400 or Highways cover would normally be specified.
What are the dimensions?
- Clear opening: 600 × 450mm
- Overall frame: 710 × 560mm
