发明名称 Roof guttering systems and brackets
摘要 In one preferred form of the present invention there is provided a roof rain gutter system. The roof rain gutter system comprises a drainage pipe for being positioned within and extending along a gutter. A coarse heavy filler material is placed on top of the drainage pipe for allowing the passage of rain water. A rain guttering component is positioned above a drop outlet of the gutter for directing water flowing through the drainage pipe downwardly into the drop outlet. The rain guttering component is adapted to surround the drop outlet to assist with preventing the passage of coarse heavy filler material through the drop outlet.
