Documents
The ¼ turn locks are provided in the form of kits enabling to equip manhole covers and gratings on site.
The ventilated versions of VIATOP manhole covers can be equipped with a mudpan in stainless steel comprising 3 or 4 legs of suspension resting on the ring.
If the mudpan is equipped with a mistake proofing leg, it is necessary to place this one in the opening box
The covers of ventilated VIATOP manhole covers have notches in their skirt enabling to remove all interactions between the cover and the mudpan.
There exist versions of VIATOP manhole covers non-ventilated also having these notches.
