Manufactured in 0.7mm lightweight and durable zinc. Corner brackets help to guide the rainwater around all the angles to sustain a well-running and effective system, they are designed to fit perfectly around the larger corners of your property such as conservatories, garden sheds or bay windows. Zinc Gutta’s 135-degree internal corner is a key and integral part of your guttering system. It's highly recommended to position the corner parts within 150mm of the fitting alongside a fascia bracket as a way of preventing water from pooling inside. In the long term this could cause the guttering to stag, forcing unneeded stress on joints which could ultimately lead a slower flow rate.
