A galvanized 4-hole open 60-degree angle is a metal bracket used in construction and carpentry. It is made of galvanized steel, which means it has been coated with a layer of zinc to protect it from corrosion. The 4-hole open designation indicates that it has four holes for screws or bolts, and the 60-degree angle describes the angle at which the bracket is bent. These brackets are used for joining or reinforcing wood or metal components at a 60-degree angle, providing stability and support in various structural applications.
