Abstract
Abstract A unitary plastic molded snap-on end cap for gutters constitutes a vertical end wall having a pair of flanges projecting outwardly normally about the periphery of the end wall from both sides thereof so that the same molded article may be used to cap either left-hand or right-hand open ends of gutters. Positive engagement of the gutter and the cap is provided by forming a groove in the cap having a rib which engages a projection formed on the gutter wall before the cap is applied thereto.
