ECE Universal Arms (hydraulic and mechanical)

Each arm features fast "One Twist", 360º adjustable design, and powerful magnetic base. Hydraulic Arms don't lose position when released like mechanical styles do, so fine adjustments are a snap. Use the ECE-300 series hydraulic arms when maximum accuracy and fast setups are important.

  • Hydraulic arms are faster, stronger,
    and more precise than mechanical joints.
  • Hydraulic joints make fine adjustments easy
  • Check T.I.R. right on your machine
  • Powerful magnetic base
