GRÖMO ALUSTAR flat-roof branch

    The GRÖMO ALUSTAR flat-roof branch can be easily combined with all common
    flat roof drainage systems and creates beautiful accents within the design of the
    exterior façade. Thanks to the pre-mounted gasket in the connecting pipe, mounting the flat-roof branch could not be easier. It is placed on the flat roof attic drainage pipe, and is simply connected to the downpipe. The perforated plate prevents the ingress of leaves, and ensures sufficient ventilation of the downpipe in heavy rain.
