PP plastic cover dn315mm, for telescopic pipe, load class A15 (increased resistance up to 3t), round, for smooth rising pipe 315mm, perforated for rainwater drainage DTO315D

Telescopic cover for manholes

The KARMAT DTO315D telescopic cover is a solid solution for securing manholes with a diameter of 315 mm. Made of high-quality polypropylene, it is characterized by increased load resistance – up to 3 tons (30 kN), as confirmed by laboratory tests. This is particularly important in places exposed to pedestrian traffic, vehicles or variable weather conditions.

The cover is designed for mounting on smooth rising pipes with a diameter of 315 mm and is an element of the rainwater drainage system. The openwork construction ensures free water flow, minimizing the risk of debris accumulation.

Design and benefits of use

The design of the KARMAT telescopic cover allows for easy height adjustment and adaptation to the surrounding surface during installation. This compensates for ground movements and changes in surface level, which often occur during the winter period, preventing damage to both the cover and the surroundings. The polypropylene used is resistant to low and high temperatures and UV radiation, guaranteeing long-term operation without discoloration or loss of mechanical properties.

• Strength: Class A15 (3 tons) ensures safety even in areas with heavy traffic.
• Durability: High-quality polypropylene resistant to weather conditions and mechanical damage.
• Adjustment: Precise adjustment to the surface level during installation.
• Movement compensation: Effectively levels changes in ground and surface level.
• Water flow: Openwork design prevents debris from accumulating inside the manhole.
• Versatility: Designed for smooth pipes with a diameter of 315 mm in rainwater drainage systems.

Application and compliance with standards

The KARMAT DTO315D telescopic cover is used in both residential and commercial construction, as well as in urban infrastructure. It is suitable for private properties, parking lots, sidewalks, playgrounds and other places requiring safe and durable protection of manholes. It provides effective protection against unauthorized access and prevents dirt and rainwater from entering the manhole.
