To connect aluminum extrusions end to end, you typically use end-joints which utilize specific inserts.
Unlike screw ports used for attaching other components to an extrusion, end-joints are specifically designed to let you seamlessly connect extrusions end-to-end. This method provides a sturdy and clean connection between profiles.
Understanding End Joints and Inserts
End joints are a fundamental part of modular framing systems using aluminum extrusions. They facilitate joining two profiles directly at their ends. The key components of an end joint are the inserts, which fit inside the core or T-slot of the extrusion profile.
Common types of inserts mentioned for this purpose include:
- Couplings: Often used to extend extrusions in a straight line. They fit internally within the extrusion's core or T-slots to provide structural integrity across the joint.
- Cleats: Can be used for both straight extensions and, significantly, to create sturdy corner joints where two extrusions meet at an angle (commonly 90 degrees) at their ends.
By using these inserts, end joints can either extend extrusions in the same direction for longer spans or create necessary corner configurations for frames, structures, or assemblies. The seamless connection achieved ensures structural stability and a clean aesthetic.
