The SL25-02 is a StarModul L-joint for 2.5×2.5 cm square tube. It connects the top of a post to a horizontal beam, forming an L. It is assembled screwed, without welding, and includes the Screws.
It is used at the ends of portals and single-beam frames. The 2.5×2.5 cm tube is for small, lightweight structures, where a slim line and a clean finish are required. See the 3D viewer on this page to view 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 galvanised steel tube (1.5 mm thick); we can send it cut to size.

Yes. Each joint is supplied with its Screws.
No. The entire StarModul system is screwed, so it can be assembled and dismantled 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.
