Rite·Lock™ for STS Series


Roll·Rite® STS Series systems feature our Rite·Lock power kit arms that consist of a specially treated, high strength extruded aluminum alloy. Combined with our patented knuckle pivot technology, our power kit arm provides smooth, compact operation for side roll tarping. Single or Dual Arms systems are available based on your application. Mounting options are also available based on your application.

  • Patented Knuckle Pivot… allows axle to climb heaped loads and keeps constant tension on tarp for maximum control in wind conditions
  • Low-Profile Arm… keeps tarp operation within inches of your trailer top, reducing overhead hazards
  • Lock-Down Coverage… offers maximum load protection and containment, especially with a solid tarp for sealed applications
  • Pre-Assembled & Pre-wired… arm for faster, easier installation

From rear tarp returns to spring bows, Roll·Rite® can fully equip.

  • Spring-Powered Rear Tarp Return … is industry’s first patented spiral torsion spring-powered return for single arm side roll tarp applications. Self contained, chrome finished rotary unit powers a heavy duty 1-inch webbed strap for improved weather resistance and longer life than common bungee returns. Provides 3-times the pull back force of common bungee returns.
  • Composite Bows with Brackets… new fiber composite bows now available are stiffer and retain shape unlike common nylon bows on market. Half-round shape is sized to retro-fit existing brackets and allows for doubling up half round bows creating a full round install for applications requiring added rigidity
  • End Caps… fabric end caps are recommended for most end dump trailer applications. Solid (aluminum) end caps for a rigid installation are available as custom order.
