Description
Specially developed for modern, wide-angle corner joints and left-facing aesthetic transitions in your modular structure projects, the 4040MA03-3 22.5° Wide-Angle Corner Connector combines structural flexibility and design in frames built with 40×40 mm profiles. Thanks to its three-way connection capacity and fixed 22.5-degree wide angle, it provides both superior stability and a smooth appearance at corner points.
Why the 4040MA03-3 Corner Connector?
-
Left-Facing Modern Wide Angle: Offers a wide 22.5-degree opening at the left corner details of your project, allowing you to create airy and modern forms that go beyond standard right-angle designs.
-
Flawless Three-Way Joint: Joins three different profiles at a single point with millimeter precision, providing maximum load distribution and resistance at the frame’s most critical corner points.
-
No Welding Required: Allows you to professionally complete complex low-angle corner joints using only simple hand tools, without any welding or technical cutting processes.
