Description
The 4040ER04-1 60° Angled Single-Direction Purlin Ridge Connector, which solves the transition from right-angle ridge lines to steep-pitched purlins at a single point in your modular structure projects, forms the most critical joint point in roof systems built with 40×40 mm profiles. Thanks to its fixed 60-degree right angle and single-direction purlin outlet, it allows you to join complex roof geometries with high engineering precision.
Why the 4040ER04-1 Ridge Connector?
-
High-Pitch Design Flexibility: With its 60-degree right angle, it connects purlin and ridge profiles in steep-pitched roof forms with unshakeable integrity.
-
Precise 60-Degree Fixing: It fixes the angle shifts that are the biggest problem in steep-pitched roofs down to the millimeter, completely eliminating manual measurement and cutting errors to create a flawless roof line.
-
No Welding Required: While bringing four different profiles (ridge and purlins) together at one center point at a 60-degree angle would normally require very challenging welding work, with this product you can perform a professional installation using only simple hand tools.
-
Durable Structure: Manufactured using the high-quality aluminum injection casting (HPDC) method, it offers superior strength at the most critical joint points against snow, wind, and static loads on the roof.
Areas of Use: It is the ideal solution for steep-pitched modular roofs, A-Frame houses, decorative steep-roofed garden sheds, tiny house ridge joints, and custom-designed aesthetic DIY frames.
