描述
390mm aluminum spigot ladder truss is a larger two-chord ladder truss for exhibition display frames, DJ lighting structures, speaker support, banners, showrooms, retail displays, bars, clubs, and temporary event layouts. Compared with 290mm ladder truss, the 390mm profile gives more structure depth and can be a better fit when the project needs a stronger visual frame and suitable lightweight span capacity.
The old product reference notes that this 390mm aluminum spigot ladder display truss can be produced in custom lengths up to 6m and joined with conical connection couplings. Final span and loading should be confirmed according to the complete layout, support method, hanging equipment, connection details, and venue conditions.
