ABSTRACT:
The present invention relates to an eavestrough fitting having a molded plastic member with a gasket secured thereto having a unique configuration. The gasket has at least two ribs extending across the molded plastic member and up the sides thereof, with these ribs being sized to form a seal with an appropriately shaped eavestrough inserted within the fitting. The eavestrough is inserted into the fitting and the gasket includes resilient aligning members urging the sidewalls of the inserted eavestrough towards the center whereby the base of the eavestrough is more positively urged into sealing contact with the ribs across the base of the molded plastic member.
