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 6-Inch Gutter sections at 45° angles to form the outside corner joint; ensure clean, precise cuts for proper alignment on large system installation.
  2. Test fit assembly: Position Gutter sections to form 90° outside corner; verify proper alignment and adjust cuts if necessary before final installation of high-capacity system.
  3. Apply sealant generously: Place continuous bead of high-quality Gutter Sealant along both Gutter edges where Strip Miter will overlap on the large system outside corner.
  4. Position Strip Miter: Center strip over the outside joint ensuring equal overlap on both 6-Inch 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 large system 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 on high-capacity application.
Maintenance
  1. Inspect exposed sealing: Check Strip Miter seams seasonally for cracks, gaps, or sealant failure at the exposed large system outside corner; reseal promptly to prevent water infiltration.
  2. Monitor fastener integrity: Verify Rivets or Screws remain tight and corrosion-free on the exposed high-capacity 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 in large systems.
  4. Check weather exposure: Ensure Strip Miter remains properly positioned and hasn't shifted due to wind load, thermal expansion, or ice formation on large gutter installation.

Compare Styles & Materials

6-Inch Outside K-Style Strip Miter vs Other Options

  • 5-Inch System: Handles up to 1,400 sq ft per Downspout, easier installation, lower cost, standard for typical applications.
  • 6-Inch System: Handles up to 2,400 sq ft per Downspout (40% more capacity), required for large roofs, higher cost, essential for commercial buildings.

When to Choose 6-Inch Outside Strip Miters

  • Large residential homes (over 1,400 sq ft per downspout) requiring budget corner solutions
  • Commercial buildings needing economical high-capacity corner coverage
  • Repair work on existing 6-Inch Strip Miter systems
  • Budget-conscious projects where cost is the primary concern for large gutter installations

Strip Miter vs Box Miter for Large Systems

  • Strip Miter: Lower material cost, requires more labor and sealing work, adequate for budget applications on large systems, more visible seam lines, potential need for paint match work.
  • Box Miter: Higher cost but cleaner appearance, faster installation, more color options, superior weather resistance, preferred for exposed large system corners.

Best Choice: Use 6-Inch Outside Strip Miters for budget-conscious large Gutter projects, repair applications, or when matching existing strip miter systems where cost is the primary concern.

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.

Will this work with 5-Inch Gutters?

No. This Strip Miter is sized specifically for 6-Inch K-Style Gutters only. Contact us for 5-Inch Outside Strip Miter options if needed.

What's the difference between 30° White and 80° White?

30° White has a flatter finish that accepts paint more easily, making it ideal for projects requiring custom color matching. 80° White has a slightly glossier finish that matches most standard Gutter Systems.

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 for large systems. The flat profile and exposed seams require quality sealant and periodic inspection.

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 on large installations.

What's the best sealant for large system 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.
