How It Works
The bar attaches across the rear of the trailer
The tarp either:
Slides through the bar (via a pocket), or
Hooks onto it using J-hooks or fasteners
When the tarp is pulled over the load, the bar:
Stretches and stabilizes the tarp
Keeps it snug against the material being hauled

Compliance: Helps meet road tarping laws in many states
Durability: Reduces tarp wear caused by wind whipping
