Norocking Manhole D400

Description

Inspection manhole cover in ductile iron EN-GJS-500-7 conforming to norm UNI EN 1563:2012

FRAME

It is realized in a single casting with a height of 100 mm, it ensures stability through a coupling system, obtained by interposing an EPDM corner seal in the corners of the frame, in order to ensure the reduction of vibration and the absence of noise during use. Externally, its structure helps to optimize the seal of the cement mortar and the insertion of anchoring devices.

COVERS

It comes square in shape, it guarantees stability thanks to its depth of insertion and to the support of EPDM gaskets. The closing system is realized through an elastic bar included in the cover, which creates an automatic opening and closing system, this can be performed with building clays. On the surface it presents two or four blind holes for the insertion of suitable lifting handles. The covers are interchangeable, the upper surface is designed to be antiskid, to allow the complete flow of runoff water and avoid the creation of ice.
