PP plastic cover dn315mm, Class A15 (increased resistance up to 7.5t), round, for corrugated riser pipe DN/OD355mm, solid P355

Manhole cover – durability and safety

This round polypropylene cover, designed for corrugated riser pipes with a diameter of 315 mm, is a reliable finish for manholes. Made of high-quality plastic, resistant to weathering and mechanical damage, it provides long-lasting protection and functionality. The cover is characterized by increased strength – class A15 means it can withstand a load of up to 7.5 tonnes (75 kN), as confirmed by tests in accordance with EN 124 standard. This guarantees safety in areas exposed to pedestrian and bicycle traffic.

Design and application

The KARMAT full cover fits perfectly with corrugated pipes with an outer diameter of 355 mm. Its design ensures a tight seal of the manhole, protecting against the ingress of dirt and moisture. It is used both in soakaway wells for drainage, garden inspection chambers, and in more demanding applications – such as sewer inspections on sidewalks or green areas. Installation is simple and quick – the cover is mounted directly to the corrugated pipe using two screws (included). No need to use additional seals further simplifies the installation process.

Advantages for professionals and end users

• Strength and safety: Load class A15 guarantees safe use in areas with medium traffic intensity.
• Weather resistance: Polypropylene provides resistance to UV radiation, temperature changes and the effects of moisture, which translates into a long product life.
• Easy installation: Quick and easy installation with screws minimizes working time and installation costs.
• Tightness: The full cover design prevents contaminants from entering the manhole.
• Lightweight: The weight of the cover (1.7 kg) makes it easy to transport and install, especially during work at height or in hard-to-reach places.
• Aesthetic appearance: The green color of the cover blends well with the surroundings, especially in green spaces.
