Zinc Gutta's roof brackets are manufactured from a sturdy stainless steel. The intended purpose of a roof bracket is to be fitted into the exposed roof truss to achieve a system that is aligned to ensure the most efficient flow rate. Zinc Gutta roof brackets are often used in cases where there is no fascia board in place. If you're looking for the easiest way to install them, Zinc Gutta recommends fitting the brackets either 600mm - 800mm apart, with one being placed the beginning and end of the straight gutter section. The brackets can be tailored to meet the requirements of your guttering system by being twisted or bended using a vice. Zinc Gutta Large Half Round Roof Bracket Dimensions Width: 185mm
