Outer Frame High Strength Engineering Plastic Corner Bracket for Hidden Mesh Screen Window

Outer Frame Corner Brackets
These corner brackets are specifically designed for the outer frames of invisible-mesh Screen Windows. Made from high-strength engineering plastic via injection molding, they are used to reinforce and join the horizontal and vertical profiles at 90° corners, making them an essential hardware component for assembling Screen Window frames.

High-Strength Engineering Plastic Base Material: Exceptional Toughness and Durability
The main body of the corner bracket is injection-molded as a single piece from high-toughness engineering plastic. It offers excellent impact resistance and resistance to aging, enabling it to withstand the frame’s own weight and external vibrations over the long term, while preventing fractures or brittle cracking at corner joints. Resistant to sun and rain, they resist fading and aging even with long-term outdoor use, offering high stability and making them ideal for Screen Window installations. They feature built-in nut holes; once screws are tightened, they lock securely in place, preventing stripped threads or loosening.

Precision-Aligned Structure Ensures a Square and Stable Frame
The product is precision-molded to fit snugly into the corner chambers of the Screen Window profiles, securely locking the horizontal and vertical aluminum profiles in place and maintaining a stable 90-degree angle. This effectively prevents issues such as frame warping, diagonal misalignment, and widening profile gaps that can occur with long-term use, thereby enhancing the sealing performance and structural stability of the entire Screen Window frame from the source.

Pre-set Standard Lock Holes for Efficient and Quick Assembly
The corner brackets feature built-in standard nut slots. During assembly, simply insert them into the corner cavities of the profiles and tighten the matching screws to complete the outer frame assembly. No additional slotting or milling is required, significantly reducing assembly time at the Screen Window manufacturing plant. This saves time and effort in mass production and makes subsequent Screen Window disassembly, installation, and maintenance simple and convenient.

Wide Range of Applications
Primarily used to reinforce the corners of hidden-mesh Screen Windows, these corner brackets can be shipped together with the complete hidden-mesh Screen Window hardware system. They are suitable for the production of residential Screen Windows, Screen Window installations for real estate projects, and bulk supply of Screen Window hardware for export.
