The SL25-11 is a StarModul cross joint (+ type) for 2.5×2.5 cm square tubes. It joins four tubes in a cross on the same plane. It is screw-mounted, without welding, and includes the Screws.
It is used where two beam lines cross, for example in flat roofs or multi-module structures. The 2.5×2.5 cm tube is for small, lightweight structures where a fine line and clean finish are desired. See the 3D viewer on this sheet to see the exact shape of the part.
Fit the tubes into the part, check the corner bracket, and screw. No welding or special machinery is needed, so the structure is assembled directly on-site. For this joint you need 2.5×2.5 cm (1.5 mm thick) galvanized steel tube; we can send it to you cut to size.
See also: all joints for 2.5×2.5 cm tubes without flanges and the 3D structure configurator, which calculates the joints and tubes for your project.
Yes. Each joint is delivered with its Screws.
No. The entire StarModul system is screwed, so it is 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.
