The 0105-12 is a T-joint for StarModul subframes for 10×5 cm rectangular tubes. It forms a T within the structure to create the subframe for a window or door. It is screw-mounted, without welding, and includes the necessary screws.
It is used in enclosures to prepare window or door openings. The 10×5 cm rectangular tube provides more depth than the 5×5 cm one with little weight, and works well as a beam or purlin in frames and roofs. Check 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 bolt it together. No welding or special machinery is needed, so the structure can be assembled directly on site. For this connector you will need galvanized steel tube, 10×5 cm (2 mm thick); we can send it cut to size.
