This is a 3D CAD model of a curtain wall mullion anchor assembly mounted at the front of a concrete slab. The assembly features a reinforced mullion extrusion, a steel angle bracket, and slotted anchor plates with bolted connections for both vertical adjustment and structural support. This anchoring method is commonly used in high-rise glazing systems where the curtain wall is installed outside the floor slab edge, allowing for thermal insulation continuity and clean architectural lines.
