  • Dual air supply at one end eliminates tubing going to the opposite end of the cylinder - preventing interference with the operation of the device
  • Extruded tube construction requires fewer supports than other cylinders
  • Stainless steel tie bolts and aluminum spacers lock precision machined heads tightly around a unique, high-strength, composite cylinder tube
  • Extremely smooth tube with self-lubricating interior surface ensures highly reliable performance and extended seal life
  • High-impact resistance reduces chances of cylinder failure due to dings or dents
  • Zero slip-stick avoids problems that metal cylinders encounter when sitting in a static condition for extended periods of time
