US Aluminum IBX Inside Box Mitre

A 5" or 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 and is available in a 30 (low gloss) or 80 (high gloss) white.
