Inside corner miters are used where two gutter sections meet at an inward corner (like the inside corner of an L-shaped building), while outside corner miters are used at outward corners (like the outside corner of a building). Both create perfect 90° transitions but are engineered for their specific applications. Most homes need both types for complete gutter systems.

This miter is designed specifically for 6K gutter systems and will only work with 6K gutters. It will not fit 5K, 7K, or other gutter profiles. If you're unsure about your gutter size, measure the top opening - 6K gutters have a specific profile that this miter is precision-engineered to match. Contact us with photos if you need help identifying your gutter system.

We offer 30+ professional colors including exact matches for most standard gutter colors. Popular choices include 30 Deg. White, Dark Bronze, Musket Brown, and Black. If you have existing gutters, take a photo in natural light and contact us - we can help identify the closest match. For custom projects, we also offer color matching services to ensure perfect coordination with your exterior.

Professional installation is strongly recommended for several reasons: working at height requires safety equipment and expertise, proper sealing techniques are critical for leak-proof performance, and precise alignment is essential for optimal water flow. Improper installation can void warranties and create expensive water damage. Professional contractors have the tools, experience, and insurance for safe, guaranteed installation.

Each box miter includes the precision-engineered corner piece in your selected color and configuration (inside or outside). Professional installation hardware and sealant are typically purchased separately as they vary by installation requirements. We provide detailed installation specifications and can recommend compatible sealants and fasteners for your specific project needs.

Count each corner where gutters change direction - most homes need 4-8 corners depending on the building shape. Simple rectangular homes typically need 4 outside corners, while L-shaped or complex designs may need both inside and outside corners. Take photos of your roofline or contact us with your address - we can help determine exactly what you need for complete coverage.
