Thanks to their modular features SABdrain channels (of equal width) can be linked together even if they are of different heights. In this way you can obtain a progressive increase of the flow rate in the section of channel, according to an installation system called “stepped fall system”. To connect a channel having a different height to another, a stepped fall cap is required.
