• Urban silence: The special gasket and the "U" shaped seating eliminate annoying metallic noises during vehicle transit, making it perfect for residential areas.
• Operator safety: The 90° locking system prevents accidental closing of the lid during inspection and maintenance phases in the manholes.
• Simplified installation: The square frame with a continuous perimeter flange and dedicated slots ensures superior mechanical anchoring in the road foundation.
• Hermetic protection: The system design guarantees an effective barrier against infiltration and debris, preserving the integrity of telecommunication cables and joints.
• Slip resistance: The uniform non-slip surface patterns increase surface grip and facilitate the rapid runoff of rainwater, preventing traffic hazards.

The h638_14 manhole cover is the standard solution for telecommunications and fiber optic infrastructure networks located under high-traffic road surfaces. It is specifically indicated for roadways, trafficable shoulders, and parking areas where Class D400 is required. Its configuration makes it ideal for inspection chambers where technical access is frequent, guaranteeing a wide and circular passage area (clear opening), optimal for moving equipment and personnel.

Choosing this model means investing in a long-lasting and low-maintenance product. It is preferable to traditional manhole covers without hinges as it drastically reduces intervention times and the risk of injury during opening. The automatic closing system with locking lug and the provision for identification markings make it the technical tool of excellence for network managers who require a closure that is hermetic, anti-noise, and certified according to the strictest UNI EN standards.

What is meant by "90° hinge block" and why is it important?

It is a mechanical safety system that automatically locks the lid once it reaches the 90° vertical position. This prevents gusts of wind, vibrations, or accidental impacts from suddenly closing the lid while technical personnel are inside the manhole.

Does the included gasket need to be replaced periodically?

The gasket is made of material resistant to hydrocarbons and atmospheric agents to ensure a long life. However, a visual check during periodic inspections is recommended to ensure that there is no debris that could compromise its anti-noise function.

Is it possible to identify the content of the manhole externally?

Yes, the lid has a dedicated space designed for the insertion of text or logos (such as "Telephony" or company brands), allowing technicians to quickly identify the type of utility without having to open the manhole cover.
