Material Made of PP (polypropylene).

Use: Used as a valid alternative to traditional concrete wells and particularly suitable for housing hydraulic and/or electrical devices for earthed systems. The Seventy manhole is the largest on the market and, unlike traditional concrete manholes, it is produced with a removable bottom and can be lifted by a person rather than by a crane!

The cover is a PP reinforced “plate” with 5 fiber-reinforced beams, laterally interlocked on the underside. The external surface is fitted with inserts of non-slip rubber and a pair of ergonomic retractable handles.

Capacity: 35 KN (approx. 3.500 kgs / 7,700 lbs).

Material: Cover made of PP (polypropylene), fiber-reinforced nylon and rubber. Frame made of PP (polypropylene).
