GT-Series, Hydraulic Bolt Tensioners

  • Enerpac hydraulic bolt tensioners have six load cells from M16 to M95 or from ⅝" to 3¾"
  • Twin ports for quick connection of multiple tools
  • Only one size of bridge per size of load cell
  • Detachable and rotational bridge simplifies bolt tensioner positioning
  • Full bridge window
  • Piston stroke indicator
  • Black surface treatment protects against corrosion
  • Anti-slip grip for more secure handling
  • Universal and multi-use tool.
