• High Infrastructural Standard: Open Fiber approval ensures that the product complies with the technical specifications required for the most important national telecommunications nodes.
• Capacity and Durability (D400): Designed to withstand loads up to 400 kN, it is suitable for installation on road carriageways subject to heavy traffic of heavy vehicles.
• Safety Lock: The internal lug ensures that the cover remains stable and secured to the frame, reducing the risk of accidental displacement or tampering.
• Certified Installation: The holes and slots for anchor bolts allow for extremely solid mechanical fixing to the foundation, preventing the frame from detaching from the road surface.
• Pedestrian Safety: Uniformly distributed anti-slip embossing offers excellent grip, reducing the risk of slipping even in wet conditions.

The h638_135 model is the choice of election for ultra-broadband infrastructure (BUL), telecommunications networks, and fiber optic cabling. Thanks to class D400 and the 55x55 cm dimensions, it finds optimal use in urban streets, public parking areas, squares, and sidewalks, where secure and compliant protection is required for technological junction boxes subject to vehicular traffic.

Choosing this manhole cover means investing in a product technically approved by the major players of the Italian network. The robustness of GJS-500-7 ductile iron guarantees a service life above average, while the height of 100 mm ensures the necessary mass to remain stable under the dynamic stresses of traffic. It is the definitive solution for those who must build technological networks that require rigorous testing and ISO 9001 certified materials.

What is meant by Open Fiber/Infratel approval?

It means that the manhole cover exactly respects the construction, material, and load specifications required by the technical specifications for the creation of the national fiber optic network, facilitating the approval procedures for the works.

Is class D400 suitable for main roads?

Yes, class D400 according to the EN 124 standard is intended for main road lanes, hard shoulders, and parking areas accessible to all types of road vehicles (up to 40 tons).

Is a specific key needed to open it?

The cover is equipped with a standard slot designed for use with lifting keys and hooks normally used by personnel involved in the maintenance of technological networks.
