• Barrier Against Bad Odors: The internal "U" groove allows creating a continuous peripheral seal against the escape of unpleasant sewage gases, significantly improving hygiene in residential and commercial areas.
• Easy and Manageable Installation: Thanks to the low weight of only 16.5 kg obtained from the mechanical and elastic properties of ductile iron, the manhole cover is extremely simple to install and to lift during inspections.
• Optimized Pedestrian Safety: The special texture with anti-slip reliefs guarantees excellent grip for pedestrian footwear and for cycle or motorcycle tires, favoring the correct drainage of rainwater.
• Stable and Durable Anchoring: The shaped peripheral flange evenly distributes stresses on the foundation concrete, minimizing the risk of subsidence or cracking of the surrounding pavement.
• Quick Identification: It integrates an indicator of the external frame dimensions in relief on the surface, simplifying cataloging and logistics management by maintenance teams.

The h638_170 model finds its ideal placement in urbanization and light urban furniture projects. It is the perfect choice for the closure and inspection of electrical junction boxes, water meters, rainwater drainage systems, or telecommunication nodes located in sidewalks, pedestrian areas, condominium courtyards, cycle paths, public green areas, and private parking lots intended only for the occasional transit of light cars.

Choosing this manhole cover means opting for a component that is **functional, robust, and fully compliant with current European regulations**. GJS-500-7 ductile iron ensures extraordinary tolerance to road chemicals and atmospheric corrosion compared to traditional grey iron. With a height of only 35 mm and intermediate dimensions of 55x55 cm, it adapts to most standard junction boxes, guaranteeing a clean and elegant flush-to-floor result that eliminates post-installation maintenance costs.

What is meant by load class B125?

Class B125, defined by the European standard UNI EN 124, certifies that the manhole cover is designed to withstand a test load of 125 kN (approximately 12.5 tons). It is the suitable and mandatory category for pedestrian areas, sidewalks, cycle paths, and multi-story parking lots for private cars.

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

The frame integrates a "U" shaped peripheral channel. By filling this space with fine sand, thick grease, or equivalent sealing materials before inserting the lid, a continuous mechanical barrier is formed that prevents gases present in the gully from rising to the surface.

Is special or proprietary equipment needed to open the lid?

No. The lid is provided with closed-bottom slots specifically designed to accommodate standard "T" hooks or lifting keys normally used by maintenance technicians, or a common construction lever.

Do the closed-bottom slots allow mud or rainwater to penetrate into the gully?

No. The "closed-bottom" feature indicates that the cavity is internally isolated: it allows for a solid attachment of the lifting tools but prevents soil, road debris, or rainwater from filtering into the chamber below.

Is it possible to request customization with a logo of the entity or company?

Yes, the lid has a specific smooth central flat area, designed to host, upon request and for suitable order batches, the personalized casting or engraving of brands, company logos, or identification labels of the utility.
