The Manthorpe Alpha Slate Vent (GRSV30/25) can be used for high or low level roof ventilation. With the addition of a compatible flexible pipe, the vent can also be used for convenient bathroom or soil extract.

Ideal for quick, discreet installation, use this vent in place of a single, 600 x 300mm roof slate. This vent is also marked with trim lines, allowing it to be cut down for use with 500 x 250mm slates.
