Installation
Fix the box gutter into the roof structure with box gutter brackets, setting the fall at a minimum of 1:200 so water drains to the outlet. The wider base carries more water, so match the gutter to the roof area feeding it. Connect the gutter to the downpipe at the outlet and fit an expansion joint on a long run.
Applications
- Concealed internal gutters on larger roof areas
- Valley and parapet gutter runs
- Roofs where a hidden gutter with higher capacity is wanted

Frequently Asked Questions
What is the benefit of the 300mm base?
The 300mm base gives the gutter a wider water-carrying capacity, so it suits a larger roof area or a valley that feeds more water than a standard-width gutter.
Is it covered by a warranty?
Yes. The gutter is manufactured in Australian BlueScope Colorbond, so it is covered by the Colorbond warranty.
What fall does it need?
A minimum fall of 1:200 is required so water drains to the outlet. Set the fall with the brackets before fixing the gutter.
How is it priced?
It is priced per lineal metre including GST and cut to your required length with a tolerance of +200mm / -0mm.
