The SL25-18 is a StarModul ridge-start connector for 2.5 x 2.5 cm square tube. It joins, at the highest point, the two sloping beams of a gable roof, on the start or end frame (gable end). It is assembled with screws, without welding, and includes the Screws.
It is installed on the end frames of a gable roof. The 2.5 x 2.5 cm tube is for small, lightweight structures, where a slim line and a clean finish are desired. See 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 it in. No welding or special machinery is needed, so the structure is assembled directly on site. For this connector you need 2.5 x 2.5 cm galvanised steel tube (1.5 mm thick); we can send it cut to size.

Yes. Each connector is supplied with its Screws.
No. The entire StarModul system is bolted, 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.
