发明名称 GASKET SEAL
摘要 An eavestrough fitting according to the present invention comprises a moulded plastic member having an improved gasket secured thereto. The gasket has at least two ribs extending across the member and up the sides thereof with the ribs sized to form a seal with an appropriately shaped eavestrough inserted within the fitting. The moulded plastic member has a generally flat base connected to outwardly angled sidewalls which terminate in a short vertical section. The gasket conforms to the shape of the moulded plastic member and includes a raised land interior to the ribs. This raised land limits the extent of deformation of the ribs while providing a resilient base for supporting the eavestrough section within the fitting. The raised land allows the eavestrough section interior to the ribs to be in contact with the land and the lower surface of the eavestrough such that grit and other debris has less of a tendency to become lodged beneath the eavestrough section.
