MANHOLE PLUG FROM 800 - 850 MM Ø

The manhole plug 800–850 mm safely closes manholes with a diameter of 780 to 870 mm and can also be used for leak tests. Slight unevenness is no obstacle for the rubber material.

Natural rubber with a fabric insert keeps the plug dimensionally stable, weatherproof and temperature-resistant. The bypass is fitted with a Storz C coupling.
