EK-telescopic cones

With the EK telescopic cone, we have combined the best features of a concrete cone and a telescopic cover system.

The EK telescopic cone is equipped with two O-ring seals that securely hold the Ø630 mm telescopic pipe in place while ensuring a watertight connection. Height adjustment is easy throughout the different stages of installation, allowing the manhole to be precisely aligned with the final ground level.

The telescopic design speeds up installation and reduces the number of components and joints required. It is compatible with a wide range of frames and cover systems, making it a versatile solution for different applications.

A cost-effective and maintenance-free solution for modern manhole construction.
