Structure: Aluminum alloy body, pre-installed high-strength set screws (hex socket) at the bottom, with locking screws on the side.
Process: The set screws directly press against or penetrate the profile wall to form a rigid connection.
Features: Extremely high load-bearing capacity with zero positional shift; high tensile strength, suitable for long-span mullions and cross mullions. Requires pre-marking and positioning before installation; Not adjustable after installation.
Application: System windows, sunrooms, curtain walls, heavy-duty broken-bridge aluminum, and high-load scenarios with large glass panels.
