The 0055-03I is a left-hand L connector with StarModul slope for 5×5 cm square tube. A corner piece that joins the post with a horizontal beam and the sloped roof beam. This is the left-hand version of the piece; the other hand is sold separately. It is bolted together, without welding, and includes all fixings.
It is used on the corners of single-slope roofs and porches. It is the most common size for pergolas, porches, gazebos, and lightweight self-assembly structures. Check out the 3D viewer on this page to see the exact shape of the piece.
Fit the tubes into the part, check the corner bracket and bolt it. No welding or special machinery is needed, so the structure is assembled directly on site. For this joint you need 5×5 cm galvanised steel tube (1.5 mm thick); we can ship it cut to size.
This piece is part of: Structure – 3 x 3 Meters – 1 Slope – Posts (5×5 cm Tube), Porch – 3 x 3 Meters – 1 Slope – Posts (5×5 Tube), Structure – 6 x 3 Meters – 2 Slopes – Posts (5×5 cm Tube).

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.
