Crafted from high-grade materials, the EXTREME Gutter Miter features a precision-molded interlocking design that outperforms traditional sealants and patch jobs. It’s built to withstand extreme temperatures, UV exposure, and heavy storm flow — all while maintaining a clean, seamless look. Whether you’re a homeowner or a contractor, this is a long-term upgrade, not a temporary fix.

Gutter corners are the #1 source of gutter system failure — often due to temperature shifts, poor seals, or subpar installation. The EXTREME Gutter Miter is engineered to eliminate those weak points by providing a permanent, leak-proof solution. If you’re tired of dealing with overflowing water or stained siding caused by miter leaks, this product delivers peace of mind with every rainfall.

Roof valleys are notorious for channeling large volumes of water directly into gutter corners — often more than standard miters can handle. The EXTREME Gutter Miter is specifically engineered with a deeper trough and wider catch zone to manage that high-flow runoff. Its design slows, redirects, and contains the surge of water from roof valleys, drastically reducing the risk of overshoot, erosion, and foundation damage.
