The 1010-21 is a StarModul tube connector for 10×10 cm square tubes. It connects two tubes in a straight line to extend them without welding. It is screw-mounted, without welding, and includes the necessary hardware.
It is used to extend beams and posts when the required length exceeds that of the available tube. The 10×10 cm tube is used in larger structures or those with heavier loads: garages, large porches, roofs, and home extensions. View the 3D viewer on this page to see the exact shape of the part.
Fit the tubes into the piece, check the corner bracket, and screw it in place. No welding or special machinery is needed, so the structure can be assembled directly on site. For this connector you will need 2 mm 10×10 cm galvanized steel tube or 3 mm 10×10 cm tube; we can ship it cut to size.
See also: all 10×10 cm tube joints with flanges and the 3D structure configurator, which calculates the joints and tubes for your project.
Yes. Each connector is supplied with its screws.
No. The entire StarModul system is screwed together, so it can be assembled and disassembled without welding.

With the StarModul 3D steel structure configurator, you can define the dimensions, geometry, and initial configuration of a structure using our bolted connection system.
The tool generates a preliminary list of the necessary joints, a quantity takeoff for pipes and profiles, and an initial assessment of the configured components.
