Black Window Corner Bracket For Aluminum Door And Window Frames
Product Overview
Designed for aluminum frame fabrication, this black Window Corner Bracket provides a practical connection solution for window and door frame assemblies. The component features a compact metal body with several fixing holes and formed vertical sections, allowing secure positioning within aluminum profiles.
The shaped construction follows the geometry of frame corners rather than functioning as a flat joining plate. This design is particularly useful for aluminum extrusion systems requiring additional positioning or reinforcement around corner areas. Multiple holes provide convenient fixing locations for compatible screws and fasteners.
The black finish offers discreet appearance when installed inside dark aluminum profiles. Suitable for new frame production, replacement work, maintenance, or repair of existing aluminum window and door assemblies.

Why Choose Our Mullion Injection Bracket?
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.
