Schematic assembly — component positions are indicative. The drawing is interactive on desktop and mobile.
The gutter run is set out along the eaves with the correct fall to each drop outlet. Hanger spacing and outlet positions are fixed before any components are ordered.
The drop outlet is the transition from the gutter into the downpipe. One outlet is placed at every downpipe position along the run.
Inside and outside corners turn the gutter at the building perimeter; joiners connect standard 3.98 m lengths into one continuous sealed run.
The rectangular downpipe carries water to ground level. 90° and 65° elbows and diverters route it around eaves, returns and projections.
Pipe clips fix the downpipe to the wall; internal hangers support and level the gutter along the fascia.
The final downpipe section connects to the site drainage. A complete component take-off and packing list is issued with every quotation.
Every part is profiled for the same 5.2 inch gutter and downpipe. Standard lengths, pack rates and unit weights come from the current product list — no mixed tolerances and no missing trims on site.
