A: One inside miter strip piece in your selected size, material and color; gutter, caulk and outside miters are sold separately.
Q: How many do I need?
A: Count each inside 90 degree corner on the roofline and order one miter per corner.
Q: Why choose a strip miter over a box miter?
A: Strip miters are made from heavier 0.0270 aluminum in this line and are assembled on site at the corner, which many installers prefer for durability.

A: Yes, 6 in. Galvalume Plus 26 GA and 6 in. 16 oz solid copper variants are listed.
Q: How is it sealed?
A: After the gutter sections and miter are joined, all seams are caulked so water cannot leak or drip through.
Expert Verdict — Reviewed by the SuperArbor Pro Desk
Strip miters are the go-to where you want a heavier corner than a preformed box miter: the 0.0270 aluminum gives more metal at the joint, and the miter is folded around the gutter ends on site. Always overlap the correct side (inside miters wrap the inside of the corner), rivet or screw per your standard practice, and finish with a fully tooled bead of gutter sealant. In coastal or high-corrosion settings, the Galvalume Plus or solid copper variant is worth considering.
Sheet metal gutter miters have sharp cut edges; wear gloves and eye protection during handling, and follow ladder-safety practices when working at the eave.
