• Effective Odor Blocking: The internal "U" seat prevents the escape of unpleasant sewer fumes and underground gases, making the product perfect for installations near entrances, homes, or commercial courtyards.
• Lightweight and Practicality: Weighing only 3 kg, the manhole cover can be moved, removed, and repositioned in a few seconds by a single operator without any effort, simplifying inspections.
• Secure Mechanical Anchoring: The presence of holes for anchor bolts on the perimeter flange allows the frame to be rigidly tied to the concrete base, preventing movement or cracking of the flooring.
• Structural Anti-slip Grip: The special embossed texture prevents footwear and the tires of cycles and motorcycles from slipping, favoring the rapid flow of water layers in case of rain.
• Unique and Precise Positioning: The chamfered corners force the cover to align perfectly with the frame at each closure, guaranteeing impeccable flatness and eliminating annoying wobbling.

The h638_174 model is specifically indicated for covering small junction boxes, hydraulic vents, grounding systems, telecommunications nodes, or rainwater pits. It finds its perfect placement in pavements, pedestrian areas, condominium access driveways, public and private gardens, terraces, and parking lots for cars with light or limited vehicular traffic.

Choosing this manhole cover means opting for a **high-performance road component in a miniaturized format**. GJS-500-7 ductile iron guarantees excellent elasticity and corrosion resistance compared to old grey cast iron, eliminating the risk of sudden breakage. The reduced height of only 25 mm facilitates professional installation even on low-thickness screeds, offering a durable, economical solution fully compliant with the strict European UNI EN 124 standards.

What is meant by load class B125?

Class B125, according to the UNI EN 124 standard, certifies that the device is designed to withstand a test load of 125 kN (approximately 12.5 tons). It is the suitable and mandatory category for pedestrian zones, pavements, cycle paths, and parking lots for private cars only.

How is the 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 before inserting the cover, a continuous physical barrier is formed that prevents sewer gases and bad odors from rising to the surface.

Do the lifting slots allow rainwater to pass into the manhole?

No. The "closed bottom" feature indicates that the cavity is internally isolated: it allows for the solid attachment of standard lifting hooks or a common site lever, but prevents soil, debris, or rainwater from filtering inside the pit below.

Is it suitable for installation on high-traffic roads?

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 light vehicular traffic.

Is it possible to request customization with my Municipality or building logo?

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