Strip Miter Outside

The 5″ Strip Miter Outside and 6″ Strip Miter Outside are precision-engineered gutter components designed to seamlessly connect two sections of K-style aluminum guttering at a 90-degree outside corner. These strip miters are crafted from high-quality, heavy-duty aluminum, typically ranging from 0.019 to 0.027 gauge depending on the manufacturer, ensuring durability, corrosion resistance, and long-term performance in various weather conditions. Available in both 5-inch and 6-inch sizes, these miters are compatible with standard K-style gutter systems, making them an essential accessory for residential and commercial roofing applications.

Each strip miter features a sleek, one-piece design with a 90-degree bend, approximately 3 inches wide, which overlaps the gutter seam to create a smooth, aesthetically pleasing transition at external corners. This configuration minimizes the number of seams to a single, reinforced joint, reducing the potential for leaks compared to traditional multi-seam corner assemblies. The miters are designed to accommodate two adjoining gutter sections, each cut at a 45-degree angle, allowing for a secure and precise fit. The tolerance built into the strip miter design ensures ease of installation, even if the cuts are not perfectly aligned, providing flexibility for installers while maintaining structural integrity.

Installation is straightforward and efficient: the strip miter is fastened to the gutter ends using pop rivets, zip screws, or stainless steel screws (typically 3/8″ in length), and the interior seam is sealed with a high-quality gutter sealant, such as a tripolymer or silicone-based product, to ensure a watertight connection. For copper variants, soldering is also an option, offering additional versatility depending on the material chosen. Available in a range of finishes—including low-gloss white, high-gloss white, and various custom colors—these miters can be matched to the gutter system for a cohesive appearance.

The 5″ Strip Miter Outside is tailored for 5-inch K-style gutters, commonly used in standard residential applications, while the 6″ Strip Miter Outside supports 6-inch gutters, ideal for larger roof areas or regions with higher rainfall, providing increased water-handling capacity. Both products enhance the gutter system’s ability to manage runoff effectively, offering an additional layer of protection in heavy water flow areas by reinforcing the corner joint.

Manufactured to industry standards, these strip miters are available in materials such as aluminum, copper, or galvalume, with options for custom color coatings to suit specific aesthetic or environmental requirements. Their robust construction and reliable performance make the 5″ and 6″ Strip Miter Outside essential components for achieving a professional, leak-resistant gutter installation.
