Serve for joining duct ventilation installations with a bailing unit or roof ejector. Are adapted both for flat roofs as also for defined angles of decline to 45o. Roof lead-ins are joined with the use of steel flanges fixed on the element ends or with nipples, where flange base may also be additionally equipped with an EPDM gasket.[...]

Are adapted for mounting directly on roof bases with the use of steel flange or sleeve (muff) principle, where the bottom part of the bailing unit is directly mounted to the connector pipe on the roof base.
