These 7/16 inch by 3/4 inch plastic screen frame corners are designed for repairing or constructing aluminum window screen panels using square cut frame ends. They fit standard 7/16 x 3/4 inch aluminum screen frame material and slide securely into the open ends of the frame to create a strong ninety degree corner. The square cut design eliminates the need for miter cutting, making screen repair and replacement simpler and more accessible for homeowners and DIY users across the United States. Made from durable sandstone molded plastic, these screen frame corners provide a lightweight and cost effective solution for replacing broken or brittle corners on existing window screens or for building new screens from raw frame stock. The exposed corner design allows a portion of the corner to extend beyond the frame end, which is typical for square cut screen assemblies and helps maintain proper frame alignment. Installation is quick and does not require tools, fasteners, or adhesives, making it ideal for routine maintenance, seasonal screen repairs, rental property upkeep, or large home projects. Each package includes 20 screen frame corners to support multiple repairs or full screen builds, offering excellent value for homeowners and professionals alike. These corners are intended for standard residential window screen applications and are commonly used in houses, apartments, and multi unit dwellings. Always compare your existing aluminum screen frame dimensions to the line drawing before purchasing to ensure proper fit and compatibility.
