Key Features of Single-Phase LENGTHs
- Track Busway lengths designed for single-phase branch circuits
- Supports up to two circuits on a single run
- Continuous open slot allows plug-in units to be added or repositioned as needed
- Pre-wired for fast mechanical and electrical joining
- Compatible with all Track Busway single-phase power plug-in units
How Single-Phase LENGTHs Integrate Into ROW Systems
These LENGTHs are modular building blocks that become part of a complete ROW system when stacked or paired with additional components.
Optional: Add an unwired Steel Cable Tray as a top deck for cable management in double-deck ROW configurations.

USA TrackBusway® Single-Phase Lengths deliver modular, open-slot power distribution for commercial and industrial spaces for flexible overhead power distribution.
Each steel housing is pre-wired with two hot copper conductors + one neutral and factory sealed with end caps to form a self-contained grounded busway section ready for installation.
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.
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.
Track Busway is a scalable, adaptable overhead power distribution solution designed to support changing equipment layouts and long-term system growth.
