The Overflow Protector for Inside Miter is designed to manage high water volume at inside corners, where roof valleys concentrate runoff and increase the risk of overflow. Installed directly with the inside miter, it helps prevent water from flushing over the gutter edge and redirects it back into the gutter system.

This overflow protector is especially useful on valley conditions and large roof areas, where sudden surges of water can overwhelm standard gutter flow. The integrated tabs fit securely over the bead of the inside miter, allowing for fast, tool-free installation without altering the gutter profile.

Available in an angled 90° version, the protector matches the geometry of inside miters to maintain consistent water control at critical transition points. By keeping water contained within the gutter, it helps reduce splash-over, staining, and water damage along the fascia and wall below.

Manufactured from precoated galvanized steel, the overflow protector ages consistently with the rest of the Nordic Steel gutter system for a uniform appearance over time.
