Our proprietary heavy-duty downspout brackets are the strongest and most versatile on the market. The mounting screw is attached to the bracket using a hidden nut. Both the nut and the screw are removable, thus the same bracket can be used for either stand-off mounting or true flush mounting of the downspout. Only we have this feature. Others have a large exposed nut, which does not allow true flush mounting.Downspout brackets available in: 2 1/4″, 3″, 4″, 5″ (4.7″) and 6″ downspout sizes Downspout Bracket screws are made to screw securely into brick, stone, stucco, wood, and more.
