Screw‑Fixed Extruded Aluminium Corner Joint with Plastic Button (L×34)

The aluminum under‑plastic button fixer (L×34) is a reinforcing component used in corner joints of aluminum frames and sashes. With its engineered design and under‑button locking mechanism, it ensures uniform stress distribution, increases joint rigidity, and maintains the geometric stability of the frame. By providing a secure mechanical connection inside the profile cavity, this fixer enhances the durability, strength, and overall quality of aluminum doors and windows.
