Relevant spouting, rainwater head, down-pipe, bracket and material usage guidelines
Once spouting size has been established and material selected, the Spouting Profile Table - (seen below & available in downloadable format - left sidebar - this page) can be used to establish profiles available for the application. Please note, the maximum diameter of down-pipe is also shown on the table - larger spouting sizes may be required to allow for a suitable down-pipe connection.
Spouting Profile Table
1 - Check down-pipe size is capable of receiving the volume of water, refer to Recommended Down-Pipe Size Chart (right sidebar this page). Otherwise increase the number of down-pipes.

Each profile has a number of brackets available and selection of brackets is based on personal choice and specific requirements such as internal brackets, snow straps, fitting to walls without fascia board and colour.
The brackets available for each profile are shown in their respective sections on this web page Bracket spacings are for snow and non-snow loaded areas.
