All dimensions given are nominal.
Effective Cross Sectional Area: 7,300mm²
(Note 0mm free board – Marley brackets provide 10mm standoff for overflow)
Flow Capacity: 108 litres/minute
Wetted Perimeter Area: 228mm
Minimum Recommended Fall: 1:2000 = 0.5mm in 1m

| Maximum Catchment Area per downpipe(m²) |
146 | 117 | 97 | 83 | 73 | 65 | 58 | 53 | 49 | 45 | 42 | 39 |
* As per NZBC E1 – Surface Water, Rainfall Intensity equates to a 1 in 10 year storm and varies depending on geographic location. For example, 100mm/hr is a general rule of thumb for the Auckland region however please refer to hirds.niwa.co.nz for current rainfall intensity specific to your location.
