,Pre Formed Internal Corner Joint
This aluminum window profile internal corner joining hardware is designed for compatible extrusion-based frame systems used in window and door fabrication. The component features a formed metal configuration with multiple fixing holes and raised sections, allowing installation within the internal cavity of suitable aluminum profiles.
The pre-formed design provides consistent connection components for professional fabrication environments. Instead of manually cutting and shaping flat metal plates, fabricators can use purpose-shaped components when dimensions match the selected frame system.

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.
For accurate installation, the component must be precisely matched to the profile. Fabricators should verify profile channel dimensions, hole locations, connector thickness, folded section geometry, and required fasteners.
Before larger production orders, testing one sample against the intended aluminum extrusion is recommended to confirm fit and installation requirements.
This product is ideal for aluminum window manufacturers, door fabricators, building hardware suppliers, and maintenance professionals who require specialized internal frame connection components.
