Gutter Wedges are used when a fascia board is not installed perpendicular to the ground. Wedges will build out a canted or angled fascia so that the gutter can sit upright. Our K Style Universal T Wedge just clips over the back of the gutter on one end, and rests against the fascia on the other. Our Universal T Wedge works with both 5" and 6" k style gutters.
