Brackets should be supported within 150mm by a fascia component to ensure the guttering does not bulge. A sagging corner will mean water leaks inside, forcing the gutter to droop and ultimately cause a slower flow rate. Zinc Guttas corners are manufactured using extremely tough metals, allowing you to sit back and let the system work in any conditions without regular maintenance. It is vital to have a strong and robust corner in place within your guttering system to ensure it remains as solid a unit as possible. Corners divert the guttering around a point on your roof to guarantee a continuous water flow.
