MiterPro External 5" K-Style Gutter Miter Template

This MiterPro template mounts on the OUTSIDE face of your K-style gutter, no need to insert anything inside the channel. It cuts BOTH inside corner miters and outside corner miters at perfect 45 degree angles, so it's not limited to outside corners despite the "External" name, that just refers to how the tool attaches.

- Cuts inside AND outside miter corners, one tool, both cuts

- Exterior-mount design, attaches to the outside face of the gutter, faster setup

- Precise 45 degree angle guide for clean, professional miters

- Fits 5" K-style gutters (see our 6" version for larger profiles)

- Durable 3D-printed construction, patent-pending design

- Ideal for contractors and DIYers who want consistent, repeatable cuts

Q: Does this only cut outside corners?

A: No, despite the name, it cuts both inside and outside gutter miters. "External" refers to how the template mounts on the gutter (outside face), not the type of cut it makes.
