Description
Developed for the most critical center points requiring very low-slope and multi-directional joints in your modular structure projects, the 4040LA05-1 11.25° Angled Five-Way Surface Connection Connector offers a top-level engineering solution for frames built with 40×40 mm profiles. By coordinating surface joints from five different directions at a very shallow angle of 11.25 degrees, it allows you to flawlessly bring wide-span and sophisticated structural forms to life.
Why the 4040LA05-1 Surface Connector?
-
Maximum Five-Directional Distribution: By gathering five different profile inputs into a single center, it joins both the horizontal plane of the structure and the very low-slope surface lines with flawless rigidity.
-
Precise 11.25 Degree Slope: It fixes the 11.25-degree angle required for modern, aerodynamic, or minimal-slope roof and façade systems to the millimeter, eliminating any angle deviations that could occur during assembly.
-
No Welding Required: It allows you to professionally complete this precise shallow angle—nearly impossible to achieve with traditional methods—using only simple hand tools, without any welding or special angled cutting process.
-
Durable Structure: Manufactured using high-quality aluminum injection casting (HPDC), it offers superior strength and structural stability at center points that carry multi-directional mechanical stress.
Areas of Use: The ideal solution for very low-slope wide roof systems, aerodynamic modular structures, complex industrial DIY frames, and professional Tiny House projects requiring precise transitions.
