DIYers and homeowners dealing with window screens, these Artibetter corner brackets are exactly what you need for building or repairing screen frames. You get 40 pieces in the package - that's enough for multiple screens with plenty of extras for future repairs. Each bracket measures about 1.77x1.77x0.24 inches (4.5x4.5x0.6cm), made from sturdy white plastic that holds up well to weather and UV exposure. The 90-degree angle design is perfect for creating strong, square corners in your screen frames. Installation is super simple - no special tools required, just position them in the corners of your frame channels and they lock everything into place securely. They're versatile enough to work with different types of screen materials and frame sizes. The white color blends nicely with most window trim and doesn't stand out obtrusively. These are perfect for replacing broken corners on existing screens or building new screens from scratch. The plastic material is durable but still has some flexibility, which helps prevent cracking under stress. They create much stronger joints than just relying on frame friction alone, which means your screens will last longer and stay square. Whether you're repairing screens that have come apart at the corners or building custom screens for unusual window sizes, these brackets make the job so much easier. The quantity means you can do several windows at once or have spares on hand for future projects. They work great for both window screens and screen doors - anywhere you need to join screen frame pieces at right angles. Definitely one of those simple products that makes screen repair projects actually manageable for regular homeowners without special skills or tools.
