Bracket dày hơn để flush-mount máng ăn chim

This worked well for me on a 4x4 b/c one of the eaves is off to the side of the post allowing the fit.  As designed the mount bracket will not allow for the feeder to be flush-mounted against a flat surface.  

The modified bracket is shown in the photo in black.  The “stock” bracket is shown in grey.  Note the thickness of the bracket where it's placed up against the mounting surface.
