Inner Sash Reinforcing Aluminum Profile Corner Bracket for Hidden Mesh Window

Inner Sash Corner Bracket
This inner sash corner bracket is a 90° connecting and reinforcing accessory designed specifically for the inner sashes of hidden-mesh Screen Windows. It is used to join and lock horizontal and vertical aluminum profiles at corners, securely connecting the two profiles to ensure the Screen Window frame remains square and distortion-free. As an indispensable load-bearing connector in the complete Screen Window hardware system, it is widely compatible with Screen Window installations in both residential and commercial projects.

One-Piece Die-Cast Zinc Alloy: Enhanced Rigidity for Improved Frame Stability
The main body is formed through one-piece die-casting of high-density zinc alloy, featuring a solid and compact structure with ample rigidity and strength. It offers excellent resistance to deformation and impact, enabling it to withstand the screen panel’s self-weight and the vibrations caused by sliding over the long term, thereby preventing loosening, cracking, or misalignment at the corners. The precision-engineered die-cast dimensions ensure a tight fit with the cavities in the aluminum Screen Window profiles. Once assembled, this effectively enhances the stability of the entire Screen Window frame and minimizes gaps in the profiles caused by long-term sliding.

Positioning-type corner joint structure for efficient and hassle-free assembly
The components feature pre-drilled standard screw holes for easy installation. During assembly, simply insert them into the corner cavities of the profiles and tighten the screws to secure both horizontal and vertical profiles—no additional milling is required, effectively improving the assembly efficiency of the finished Screen Window. The corner brackets interlock with precision, firmly locking the profile angles after assembly and preventing issues such as frame warping and widening gaps caused by long-term use.

Customizable Surface Finish, Salt Spray Corrosion Resistance, Suitable for Bulk Supply
The surface finish can be customized to match the customer’s screen window frame color scheme. With excellent salt spray corrosion resistance, it can withstand long-term exposure to outdoor elements such as sun and rain, is resistant to rust and oxidation, and offers a long service life. Suitable for reinforcing the corners of the inner sashes of most hidden-mesh screen windows, it can be shipped in bulk along with the complete set of screen window hardware accessories.

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.
