Installation & Maintenance Tips

This installation information is a general guide only and may not address your specific site conditions. Always follow local building codes, safety practices, and professional methods. If you are not experienced with this type of work, hire a qualified contractor.

Installation
  1. Cut gutter angles: Cut both Gutter sections at 45° angles to form the outside corner joint; ensure clean, precise cuts for proper alignment and appearance.
  2. Test fit assembly: Position Gutter sections to form 90° outside corner; verify proper alignment and adjust cuts if necessary before final installation.
  3. Apply Sealant generously: Place continuous bead of high-quality Gutter Sealant along both Gutter edges where Strip Miter will overlap on the outside corner.
  4. Position Strip Miter: Center strip over the outside joint ensuring equal overlap on both gutter runs; press firmly into sealant bed for complete contact.
  5. Secure with fasteners: Install Pop Rivets or Hex Screws every 2-3 inches along both edges of the Strip Miter for maximum holding power on exposed corner.
  6. Seal and finish: Tool excess sealant smooth and inspect for complete coverage; ensure watertight seal at all connection points to prevent weather infiltration.
Maintenance
  1. Inspect exposed sealing: Check Strip Miter seams seasonally for cracks, gaps, or sealant failure at the exposed outside corner; reseal promptly to prevent water infiltration.
  2. Monitor fastener integrity: Verify Rivets or Screws remain tight and corrosion-free on the exposed corner; replace loose or damaged fasteners with aluminum alternatives.
  3. Clear corner debris: Remove accumulated leaves and material at outside corners during routine cleaning to prevent water backup and joint stress.
  4. Check weather exposure: Ensure Strip Miter remains properly positioned and hasn't shifted due to wind load, thermal expansion, or ice formation.

Compare Styles & Materials

Outside K-Style Strip Miter vs Other Options

Strip Miter vs Box Miter
  • Strip Miter: Lower material cost, requires more labor and sealing work, adequate for budget applications, more visible seam lines on outside corners
  • Box Miter: Higher cost but cleaner appearance, faster installation, superior weather resistance, preferred for exposed outside corner applications.

Strip Miter vs Hand Miter
  • Strip Miter: Uses flat aluminum strip to cover joint, requires precise gutter cutting, suitable for standard 90° outside corners only.
  • Hand Miter: Custom field fabrication for any angle, maximum flexibility for complex rooflines, requires advanced metalworking skills.

Best Choice: Use 5-Inch Outside Strip Miters for budget-conscious projects, repair applications, or when matching existing strip miter systems where cost is the primary concern. Choose Box Miters for new installations prioritizing appearance and weather resistance on exposed outside corners. Select Hand Miters for custom angles or complex roofline applications requiring maximum flexibility.

Frequently Asked Questions

This is a general guide only and may not address your specific site conditions. If you are not experienced with this type of work, hire a qualified contractor.

Are Outside Strip Miters more prone to weather damage than Inside ones?

Outside Strip Miters face more weather exposure than inside corners, making proper sealing and maintenance more critical. The flat profile and exposed seams require quality sealant and periodic inspection to maintain weather resistance.

How visible are Strip Miter seams on outside corners?

Strip Miter seams are more visible on outside corners since they're exposed to view from multiple angles. Box Miters provide cleaner appearance for outside corners where aesthetics matter, while Strip Miters are adequate for budget-focused applications.

What's the best sealant for outside Strip Miter applications?

Use our high-quality Gutter Sealant, designed for exterior aluminum applications. Apply generously and tool smooth for complete weather seal, as outside corners face direct precipitation and temperature cycling.

Can outside Strip Miters handle ice and snow loads?

When properly installed and maintained, outside Strip Miters can handle normal ice and snow loads. However, the exposed seams may be more susceptible to ice expansion damage compared to the more robust construction of Box Miters.

Why choose Strip Miters over Box Miters for outside corners?

The primary reason to choose outside Strip Miters is cost savings on budget projects or repair work. Most contractors prefer Box Miters for outside corners due to superior appearance, weather resistance, and easier installation on exposed applications.
