Trunking system with modular construction consisting of base elements of trunking rail and luminaire insert. Supplementary accessories such as reflectors, specular reflectors and louvres can be added simply and without tools.
The system can be expanded as desired with spotlights, tracks, emergency lighting, socket outlet modules and variable and fixed angle connection elements for the track

• modular system
• all elements within the DUS® product family have been constructed for a system module length of 307 mm and can therefore be combined and positioned within this system as desired
• track with 5x 2.5mm² or 7x 2.5mm² through-wiring as standard, expandable to 10-core
• dimmable luminaire inserts available as standard
• multiple circuits and phase preselection as standard
• emergency lighting possible
• arrangement as a single luminaire, as a trunking system or as a two-dimensional luminaire configuration with up to 6 rails attached to one system node
• simple-operation rotary catches for quick-fixing of luminaire inserts and reflectors
• rotary catches entirely of metal with colour-accentuated plastic cladding for secure fastening of inserts and reflectors
• mounting and electrical connection of inserts within rails without tools in one working step
• self-supporting rail connection for large distances between suspension points of up to 3.5m
