Rectangular Manhole 'NK Box Manhole'

Rectangular Manhole 'NK Box Manhole'

Ensure sufficient strength and durability! Capable of adapting to various conditions, it is possible to construct manholes suitable for the site!

The product is a box-shaped assembly manhole developed to improve workability. Since it only requires sequential assembly of precast components, it does not need skilled workers for complex rebar or formwork tasks. Because the top slab and bottom slab are integrated with the side walls, it has high rigidity against openings, and by using bolt connections, it ensures high integrity and water-tightness. 【Features】 ■ Easy to install ■ High integrity ■ Excellent site adaptability ■ Compatible with circular and rectangular openings ■ Stable quality

Ground manhole (sewer iron cover)

This is a reliable manhole cover essential for road maintenance.

This is a cast iron cover used as an inspection hatch for underground sewage facilities and communication conduits. We offer highly reliable products, including pressure relief types that prevent the cover from dislodging due to abnormal water pressure from inside the manhole, and automatic locking mechanisms that prevent anyone other than the administrator from removing the cover. Additionally, to ensure the security of cables and optical fibers buried underground, we also provide information box cast iron covers equipped with locking mechanisms that make it difficult for anyone other than the administrator to open and close them. 【Product Lineup】 ■ Cast iron covers for sewage systems ■ Protective covers ■ Cast iron covers for information boxes *For more details, please download the PDF or contact us.
