This IV Tower is designed with a "Lift-Assist" feature that neutralizes irrigation bag weight. Four independently adjustable hooks each safely support up to 10,000 cc of fluid. Comfortable, quick-release knobs permit vertical adjustment of hangers from 5.5 feet to 8.5 feet. This nurse-friendly design makes it easy for all personnel to change irrigation bags. The simple and reliable spring-based design means that there are no complicated hydraulics to fail or batteries to charge.
