Aluminium Square Downpipes

These modern Square Aluminium Downpipes are available with either a standard external pipe collar or an optional internal spigot that produces a clean-looking flush joint downpipe. Square downpipes can be fitted as a flush fit downpipe with concealed downpipe brackets, making it an anti-climb downpipe which makes it a great choice where a vandal resistant downpipe is required.
