Abstract: The dual position eaves trough apparatus has a mounting bracket which is L-shaped and has a vertical mounting leg and a horizontal projecting arm united to the mounting leg and extending in spaced relationship underneath the overhang of the roof. The projecting arm has a pivot base hole spaced from its outermost end for pivotably mounting an eaves trough support bar, and has a base lockmate hole spaced from the pivot base hole. An eaves trough support bar has a pivot mount structure, a first lockmate hole spaced from the mount structure, a second lockmate hole also spaced from the mount structure, and an extension portion which extends beyond the mount structure and serves as the support portion for the eaves trough. The eaves trough support bar is pivotably mounted at its pivot mount structure to the pivot base hole of the L-shaped bracket. An eaves trough is mounted to the extension portion of the eaves trough support bar.
