<p>An eavestroughing system comprises a roll-formed sheet metal eavestrough in combination with plastic injection molded fitting therefor. The eavestrough has a compactly overturned longitudinally extending edge portion along each sidewall of a thickness substantially greater than the thickness of the metal in the trough. The support fitting is formed of semi-rigid plastic and has two spaced-apart clip portions adapted to receive the trough edge portions. The fitting has a body portion with an internal surface approximating the external shape of the trough to encompass same when the trough is clipped into and supported by the plastic fittings.</p> |
