K&M Pre manufactures miters (gutter corners) for easy Gutter installations. All miters are laser cut and assembled as per the specified angle.
This type of miter (mitre) is known as a "box miter" and that's because of its shape, which is different than a strip miter.
Item needs to be secured with rivets or zip screws.
A 45° miter is commonly known as a bay miter (for bay windows), however, not all bay windows share the same angles. A 90° miter is the most commonly purchased item.
