This metal corner reinforcement plate is specifically designed for aluminum window and door frame assembly applications. The component features a formed configuration with multiple fixing holes and raised sections, allowing precise positioning within the internal corner area of aluminum profiles.
The pre-shaped structure provides a practical alternative to fabricating custom flat plates during frame assembly. The strategically placed fixing holes offer defined attachment locations, while the folded portions help position the connector within the available internal profile space.

This connector is essential for window manufacturers, aluminum fabrication workshops, building contractors, maintenance companies, and hardware wholesalers requiring reliable internal frame joining components.
Installation should always follow the specific aluminum profile system requirements. Select suitable fasteners according to the profile, connection design, and application conditions.
For replacement applications, carefully compare the original component with our product. Verify overall dimensions, hole arrangement, thickness, and formed geometry before purchase.
Mullion corner gaps are primary 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, significantly improving structural stability and weather resistance of the entire window system.
