Construction and finishThe ATK series is an extruded aluminum track built for use with A-Line track fixtures, and the
ATK04-BK is the 4' nominal section in black. The extrusion is paired with a PVC bus bar support that holds 12 gauge round bus bars, giving the rail its rigidity and keeping the conductors properly spaced along the whole run. A polarity groove is located on the face of the track to indicate the location of the grounding conductor — a small detail that saves real time when you are joining sections or dropping in a
power feed and need every piece oriented the same way. The black finish disappears against dark ceilings and beams, or reads as a deliberate graphic line on white drywall, which is why designers keep specifying it for
track lighting in modern interiors.
Electrical and safetyThis is a single circuit power distribution system designed to supply lighting units flexibly. Single hot and neutral conductors are rated for a maximum capacity of 20 Amps (2400 watts per circuit) at 120V, and the copper electrical conductors are concealed inside the low-profile thermo-plastic track section, so nothing live is exposed along the rail. With LED track heads drawing only a handful of watts each, that 2400 watts per circuit ceiling leaves plenty of headroom for a long, fully loaded run of
LED track lighting heads. The product is cULus listed, and LITELINE backs it with a 5 year warranty.

Installation and compatibilityThe track is surface mounted using the supplied mounting hardware, straight to the ceiling or to a wall. For open ceilings, lofts or sloped surfaces, suspended mounting is available with accessories ordered separately — rod kits, aircraft cable sets, canopy kits and suspension kits are all part of the ATK accessory family, along with joiners, "I", "L", "T" and "X" connectors, live end and wired end power feeds, monopoint feeds, receptacles and current limiters. The track system is compatible with all A-Line and Juno style track fixtures, accessories and connectors, which means you are never locked into a single head. Add
8.5W LED track head ATF7509-DTW-38-BK for a tone-on-tone black installation, or mix in
8.5W LED track head ATF7509-DTW-38-WH. Need a different look for another room? See

Applications and documentationIn residential projects, a 4' run over a kitchen island, a dining table or a stairwell gallery replaces three or four fixed fixtures with one flexible line. In
commercial lighting work, contractors use the ATK series for retail displays, boutiques, cafés, salons, offices, showrooms and small galleries where merchandising changes often and the lighting has to follow. Because the heads slide and rotate anywhere along the rail, a store can be re-merchandised on a Sunday without an electrician on site. Plan the run first, choose the feed that matches your supply (live end, wired end with cord, monopoint or conduit feed), and order connectors and accessories separately. The full technical PDF (ATK04-BK Spec Sheet) is available in the Documentation tab, with the dimensional drawings, the ordering guide and the complete list of compatible fixtures, feeds and current limiters.
