ECE Universal Arms Each arm features fast "One Twist"*, 360˚ adjustable design, and powerful magnetic base. Check out our new ECE-CSP310 Chip guard and print holder. *"One Twist" not available on ECE-302BL.
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.
