Manufactured in a slightly bigger size than the 90 degree corner, the 135 degree version comes into its own on larger corners such as a bay window, conservatory or garden shed. Corner brackets are crucial to guarantee your system stays intact and working around your entire property. Zinc Gutta’s 135 degree external corner is a vital part of the success of your guttering system. Corners must be supported by a fascia bracket within 150 mm of the fitting. This is to prevent water from collecting inside, which in turn would cause the gutter angle to drop down, putting stress on the joints and reducing the flow rate.
