Power may continue through abutting sections using USA TrackBusway® Joiner Inserts, or additional feeds can be added anywhere using a USA TrackBusway® Line Feed with integral overcurrent protection.
The continuous access slot accepts plug-in power taps like Power Drop Cords or Outlet Boxes anywhere along the run—no rewiring or downtime required.
Available in galvanized, white, or black finishes, and in lengths of 2.5', 3', 5', 7', and 10'.
If three-phase power drops are required, these single deck lengths can be double-decked for three-phase power distribution.

Track Busway is a modular overhead power distribution system built around pre-wired track busway lengths that suspend power where it’s needed in open-ceiling environments.
Each Track Busway layout is built from coordinated system components — including joiners, feeds, plug-in power drops, and supporting accessories — allowing projects to scale and adapt over time.
Simplify Overhead Power
Track Busway transforms open ceiling spaces with an innovative system that eliminates traditional overhead power structures, simplifying installations while maximizing flexibility.
Pre-Wired Power Infrastructure: Deliver branch-circuit power exactly where it’s needed using pre-wired Track Busway lengths. Power drops can be added, moved, or reconfigured without rewiring to support evolving layouts.
Plug-and-Play Power Access: Tool-free, plug-in power taps with multiple receptacle options provide fast, reliable access to overhead power while maintaining code-compliant distribution.
