• Odor Insulation: The "U" shaped perimeter groove allows for the creation of a continuous physical seal that prevents the escape of annoying sewage gases and vapors, safeguarding the comfort of residential and commercial areas.
• Stable Mechanical Installation: The pre-drilled holes on the frame allow for rigid fixing via anchor bolts, locking the structure firmly to the foundation and preventing movements or sinking over time.
• Excellent Weight/Load Ratio: Thanks to the elastic properties of ductile iron, the manhole cover withstands loads up to 12.5 tons while maintaining a total weight of only 31.30 kg, facilitating transport and installation.
• Certified Anti-slip Safety: The special surface embossing guarantees maximum grip for pedestrian soles and the tires of bicycles or motorcycles, preventing the risk of falls in case of rain or humidity.
• Guided and Unique Positioning: The chamfered design of the corners forces the cover to align perfectly with the frame at every closing, ensuring impeccable road complanarity and eliminating noisy rocking.

The h638_172 model is suitable for covering sewage inspection manholes, electrical junction boxes, water systems, or telecommunications nodes. It finds its ideal placement within urban centers, sidewalks, pedestrian areas, cycle paths, residential courtyards, public gardens, and private parking lots intended for the transit of cars and light commercial vehicles.

Choosing this manhole cover means investing in a reliable, durable, and ISO 9001 certified urban furniture component. Compared to traditional grey iron models, ductile iron offers exceptional resistance to atmospheric corrosion, road wear, and mechanical shocks. The 60x60 cm clear opening is the most requested standard to allow easy and quick access to underground utilities, making it the ideal solution for utility companies, condominiums, and construction firms.

What is meant by B125 loading class?

Class B125, defined by the European standard UNI EN 124, certifies that the device is designed to withstand a test load of 125 kN (approximately 12.5 tons). It is the specific and mandatory category for sidewalks, pedestrian areas, cycle paths, and private car parks.

How is odor tightness configured with the "U" seat?

The frame integrates a "U"-shaped perimeter channel. By filling this space with fine sand or equivalent sealing materials (such as thick grease) before inserting the cover, a continuous physical barrier is formed that prevents gases present in the manhole from rising to the surface.

Is a special or proprietary key required to remove the cover?

No. The cover is provided with standard eyelets specifically designed to accommodate the hooks or "T" lifting keys commonly used by maintenance crews or a common construction lever.

Can this model be installed in the center of a main road?

No. For road carriageways open to heavy or continuous traffic of trucks and buses, it is mandatory to use higher class manhole covers, specifically class D400. The B125 model is strictly limited to pedestrian areas and very light vehicular traffic.

Can customization with the Municipality or company logo be requested?

Yes, the cover has a special flat central smooth area, designed to accommodate, upon request and for suitable order batches, the casting or custom engraving of brands, company logos, or identification labels for the utility service.
