The Cell4 cellar vent has a 4″ round outside diameter male spigot which is designed to fit into a corresponding female or into the 4″ coupling. This cast iron coupling can be used to connect the Cell4 to the male of a 4″ pipe or if one of the rubbers are removed can be used as an adapter to fit into the male of a 5″ (125mm) pipe.

Please note – If the coupling is going to be used with a cellar vent that is screwed to the wall, washers, nylon bobbins or a wooden backing plate will need to be used with the screws between the wall and vent (not supplied)
