Description
Developed for critical points in your modular structure projects that require both angled and multi-directional joints, the 4040HA05-1 45° Angled Five-Way Surface Connection Connector provides superior design flexibility in frames built with 40×40 mm profiles. By supporting surface joints from five different directions at a fixed 45-degree angle, it allows you to quickly and securely bring complex structural forms to life.
Why the 4040HA05-1 Surface Connector?
-
Five-Directional Wide Connection: Thanks to five different profile inlets, it seamlessly joins both the sloped surfaces and the main frame lines of the structure at a single center point.
-
Fixed 45-Degree Precision: Locks in the 45-degree slope required for roof-wall joints or angled support lines, without the risk of technical measurement error.
-
No Welding Required: Allows you to professionally complete complex angled surface joints using only simple hand tools, without any welding or special cutting.
-
Durable Structure: Manufactured using high-quality aluminum injection die casting (HPDC), offering high strength and structural stability on surfaces subjected to multi-directional loads.
Areas of Use: The ideal solution for modular structures with sloped surfaces, roof-facade joint points, complex industrial DIY frames, and Tiny House wall-to-roof transition systems.
