Square telescopic cast iron manhole cover, bolted, KL.B125 (12.5T) with pipe d315 L=500mm, without sleeve, for 315 manhole 05.600.315.B125

Professional cast iron manhole for underground infrastructure

The square telescopic cast iron manhole class B125 is a reliable solution for sewage, water, and other underground installations requiring regular service access. The telescopic design allows for precise adjustment of the mounting height to the surface level, eliminating problems with uneven terrain or subsequent changes in ground level.

Construction and materials

The body made of high-quality cast iron ensures exceptional durability and resistance to dynamic loads. The load class B125 (12.5 tons) guarantees safe use in vehicular traffic areas. The square frame shape with dimensions matched to manholes d315mm facilitates precise seating and stabilization in the manhole opening.

The bolted system enables strong and durable fastening of the cover to the frame, preventing accidental shifting or lifting during vehicle passage. The telescopic pipe with a length of 500mm provides a wide range of mounting height adjustment.

Application and functionality

The product has been specifically designed for manholes with a diameter of 315mm, making it an ideal solution for modernizing existing infrastructure and constructing new systems. The absence of a sleeve simplifies the installation process and reduces potential failure points, while maintaining full service access functionality.

The telescopic design allows for flexible adaptation to various installation conditions - from flat surfaces to areas with slopes or irregularities. Once installed, it provides safe access to underground installations without the need to dismantle the entire structure during service work.

Operational advantages

The cast iron construction is characterized by natural corrosion resistance and dimensional stability in changing atmospheric conditions throughout the year.

The telescopic system minimizes the need for additional earthworks during installation, reducing installation time and labor costs. The bolted connection eliminates the need for welding or concreting on the construction site, which accelerates the infrastructure implementation process.
