Abstract: A mounting bracket is provided for attaching a support beam to a vertical support post at a pre-determined angle. The mounting bracket has a cavity for receiving the vertical support post, the cavity being attached to a side of a support plate at the pre-determined angle. The support plate is attached to the support beam, such that the support beam is supported from the ground at the desired angle. The mounting bracket is used in installations requiring a consistent angular relationship between the vertical support post and the support beam, such as solar panel arrays.
