This video shows how to use the gutter clip to join 2 gutters. All fittings have a centre gutter stop and insert depth lines. The gutter should be installed to this line. This allows the gutter to expand and contract without pulling out of the fitting. The Easyclip makes the jointing very easy. To make a joint, simply locate the gutter under the Easyclip at the back edge of the fitting and clip under the front edge. All fittings must be fixed to the fascia. Rainwater Systems.
