*The Rainhead (including the box gutter receiver) is stretched in the direction perpendicular to the box gutter.  These models provide a lower profile rainhead based on either the R-200 or R-300, but still accommodate box gutter widths up to 600mm depending on model. 

**This figure is also dependent on the size of the downpipe selected (for rainheads) and on the size of the downpipe and overflow pipes (in the case of sumps).  Please refer to the Dam Buster Product Technical Statement and Quick Design Guide for specific information about allowable down pipe and product size combinations for all of these products.
