Our bay miters are a one-piece system made from heavy duty .027 gauge aluminum. Bay miters function in the same way as strip miters except with a 45 degree bend instead of 90 degrees. Bay miters require two adjoining gutters to be cut on 22.5 angles and are preferred by contractors who only want one seam per corner. The seam is covered by the bay miter and is fastened to the gutter and sealed using any of the high quality gutter sealant options we offer (sold separately). We carry both the outside and inside bay miters for 5”, 6”, and select 7” gutters.
