Stop Inside Corner Overflows with 5” Extreme Miter Gutters

Solve the #1 Cause of Gutter Overflows: Inside Corners

If you’ve ever had a homeowner or building manager call you back because water shot over the gutter at an inside corner, you know the pain. Traditional inside miters and strips just can’t keep up with the volume of water funneled from roof valleys during heavy rains.

The 5” Extreme Miter Inside Gutter Corner is designed to fix that — with an enlarged catch basin that channels water through the gutter trough, not over it.

FAQs

Why do inside corners overflow more than other spots?
 Roof valleys concentrate a large amount of rainwater into one spot, often overwhelming traditional inside miters.

How does the Extreme Miter fix this?
 Its enlarged catch basin collects and redirects water into the gutter trough, keeping it off the fascia and siding.

Can I use this with other gutter guard systems?
 Yes — it integrates with most 5” gutter guards and standard K-style gutters.

Is installation different than standard miters?
 No — install it the same way you’d install any inside miter, but enjoy much better water control.

Control Valleys. Prevent Callbacks.

Don’t let roof valleys turn into overflow headaches. The 5” Extreme Miter Inside Gutter Corner helps keep your installs watertight and your customers happy — even during the heaviest downpours.
