Improve Safety

Significantly improve safety over improvised solutions such as inverted casters.

  • Low-profile design minimizes the height of the supported load
  • Designed for higher angled loads created by v-block type support
  • Fail-safe structure is designed to provide stable support for the load in the event of dramatic overloading leading to roller failure

Work Efficiently

  • Non-marring durable, and low friction solid acetal rollers
  • Constructed of corrosion resistant or coated materials
  • Blocks can be mounted with central 1/4 inch hole which is counterbored for a socket head cap screw
  • Compact and lightweight design is easy to transport


  • Two standard sizes to accommodate diameters up to 14 inches
  • A locking option which adds one thumbscrew per block and tapped holes to allow it to be used to lock either roller in any position.
