1×1 to 1×2 Aluminum Tube Connector | TS400 | Tube²

The TS400 is a four-way transition connector designed to join two 1" × 1" aluminum tubes and two 1" × 2" aluminum tubes at a single planar intersection. Opposing sockets create continuous frame runs in both directions, allowing square and rectangular tubing to intersect at 90 degrees while maintaining clean alignment. The TS400 is ideal for modular wall grids, partitions, display systems, shelving frameworks, panel supports, and other mixed-profile structures requiring intersecting frame members without welding or custom-fabricated brackets.
