For Hangers used with Half-Round Copper Gutters, K-Style and Box Gutters
K&M's Gutter Wedge is manufactured form 3/16" copper bar stock. The dimensions and angles change along with the roof pitch in order to hang a gutter correctly. A mounting hole is provided at the very top of the wedge and a optional hole is also provided at the back from sizes of pitch 3 and up. This gutter wedge will work with most gutter hangers than can accept a 1/4" bolt for attachment through the back. It works with our #15 half round gutter hanger and our copper cross bar hanger. It is important to note that all dimensions and angles assume that the fascia board is perpendicular to the roof line, meaning it measures 90° off the roof. This should always be the case when the fascia is angled, however, it may not be, so please double checking before ordering. When a hidden hanger is used (as the crossbar hanger in the examples shown), a hole will need to be drilled in the back of the gutter to mount the wedge with the provided bolt.
Measuring the pitch
The pitch or the angle of a roof is calculated by how many inches it rises vertically for every 12 inches it extends horizontally. For example, a roof that rises 6 inches for every 12 inches of horizontal run is called a 6 pitch or a 6-12 pitch. If drawn on a piece of paper, this triangle would have a 26.57° angle off the horizontal line (the wall line). A different example is a 12-12 pitch, where the rise is 12" over a 12" span, creating a 45° angle. A flat roof would have a 0 pitch.
