US Aluminum 6IBX30WHITE Inside Box Mitre 6" 30 White 20ct

 A 6" inside box miter is a corner piece that connects two pieces of gutter at an inside corner on a roofline. Inside box miters provide an extra degree of protection against gutter failure. They can help prevent overflowing from a roof valley in heavy rainwater conditions. Inside box miters are made from two short pieces of gutter material that are factory seamed together at a 90° angle. This order is for 20 pieces.  The color is 30 (low gloss) white.

 Professional installation is highly recommended.
