Description
Designed to extend profile lengths or join two profiles into a rock-solid, continuous line in your modular structure projects, the 4040LN02-1 Two-Way Straight Connector ensures continuity in 40×40 mm frame systems. By bringing two profiles together end to end at a full 180-degree angle, it preserves structural strength over long runs and offers an aesthetic transition.
Why the 4040LN02-1 Straight Connector?
-
Linear Extension Advantage: In wide-span projects where standard profile lengths fall short, it allows you to confidently join two profiles as if they were a single piece.
-
Flawless 180-Degree Alignment: The connector’s internal socket structure keeps the joined profiles on the same axis, completely eliminating any bending or axis misalignment that could occur during assembly.
-
No Welding Required: While welding two box profiles end to end requires laborious and precise workmanship, with this product you can create a strong, clean joint in seconds using only simple hand tools.
-
Durable Structure: Manufactured using high-quality aluminum injection die-casting (HPDC); it fully matches profiles with 2 mm wall thickness, providing high resistance against tensile and bending loads.
Areas of Use: The ideal linear joining solution for wide-span shelving systems, long booth walls, modular fence and railing lines, Tiny House ceiling rails, and all long-run DIY frame projects.
