The SL25-13 is a StarModul straight-outlet wall connection for 2.5×2.5 cm square tubes. It is a straight-outlet anchor plate: it fixes the tube perpendicular to a flat surface, whether the floor, as a post base, or a wall. It is screw-mounted, without welding, and includes the Screws.
In StarModul kits, it is used as a base for posts, anchored to the floor; it also serves to start beams from a facade. The 2.5×2.5 cm tube is for small and light structures, where a fine line and a clean finish are desired. View the 3D viewer on this page 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 connection, you need 2.5×2.5 cm (1.5 mm thick) galvanized steel tube; we can send it cut to size.

Yes. Each connection is delivered with its Screws.
No. The entire StarModul system is screw-mounted, 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.
