This Window Corner Bracket is designed for corner joining applications in compatible aluminum window and door frame systems. Its formed construction includes a wide mounting section, several fixing holes, and raised metal portions that allow the component to occupy a specific position within the internal frame structure.
The bracket provides a practical connection point when two sections of an aluminum profile need to be joined around a corner. The pre-formed shape helps simplify assembly compared with creating a custom connection plate from raw material.
The black finish provides a discreet appearance inside the frame and is particularly suitable for dark aluminum extrusion systems. The multiple holes offer flexible fastening possibilities depending on the profile design and installation requirements.

This Window Corner Bracket can be used for aluminum window fabrication, door frame assembly, renovation, maintenance, and replacement hardware applications. It may be suitable for professional window manufacturers, aluminum profile fabricators, construction contractors, and replacement-parts distributors.
Mullion corner gaps are one of the main causes of window water leakage and air infiltration. Our Mullion Injection Bracket serves as a reliable positioning fixture for glue injection. The injected sealant forms a complete sealed layer at the middle column corner, greatly improving the structural stability and weather resistance of the whole window system.
Compatibility should be carefully checked before purchase. Customers should compare the bracket with existing frame hardware and confirm dimensions of mounting holes, overall bracket size, folded sections, and profile channel. The correct fasteners should be selected according to the specific aluminum frame system.
Because window and door extrusion systems differ in internal dimensions, a bracket that fits one profile may not necessarily fit another profile with a similar external appearance.
We are a professional manufacturer of door and window accessories. Our full product portfolio includes Drain Cover, Aluminum Corner Joint, Waterproof Sticker, Silicone Windproof Block Series, Sliding Window Anti-Collision Adhesive, Glass Fan Diagonal Adjustable Cushion Block, Silicone Handle Protective Cover, and Mullion Injection Bracket.
We offer factory direct prices, strict quality control and fast shipment for global buyers. Welcome to contact us for samples, catalog and quotation.
