Downspout Sizing
Please refer to our Gutter Sizing publication contained in our Designer’s Kit to properly select both gutter and downspout size. Material thickness selection for extruded downspouts is a matter of its size and the die requirements of the extruder. Sizes shown are fixed and cannot be
altered.
The Designer should consider using extruded downspouts
for projects subject to abuse, vandalism, or where waterproof downspouts are required. Downspouts are not designed for internal building installation.
