  • Optional cycle counter – For maintenance scheduling purposes all Aero WTB Tools offer an optional mechanical pressure cycle counter
  • Swivel connection – 360° swivel operation allows the hydraulic hoses to be positioned in the best possible position to allow open access to the tensioning tools
  • Geared nut run-down – The inclusion of a gear nut run-down mechanism offers a very rapid and consistent way of seating the hexagon nuts during the tensioning procedure
  • Best fit – The interchangeable profile cut spacer at the base of the tool gives the tensioner the flexibility to be used in many different applications
