Fitting notes
Space fascia brackets at 800–1000mm centres. The square downpipe pairs with square running outlets and offset bends.
Fix an extra bracket within 150mm of every union, angle, running outlet and stop end, and lay the gutter to a slight fall of about 3mm per metre (1:350) towards the outlet. Leave the manufacturer's 6–10mm expansion gap at union joints, and space downpipe clips no more than 1.8m apart with support near the top and bottom of the run.
Colours
White, Black, Brown, Grey and Anthracite Grey.
Compatibility
