TOOL SUSPENSION & FALL SUPPORT: No power source necessary. Holds and stabilizes tools. Ergonomically beneficial/efficient by alleviating tool's weight and worker fatigue while completing repetitive tasks. LIGHT WEIGHT: Zero gravity balancer makes tools feel virtually weightless and maximizes efficiency and accuracy while operating. Adjustable tension and cable length. WORKPLACE SAFETY: Prevents tools from falling in the event of spring/tension failure. Keeps the work environment safe and the workplace clear of tools, fixtures, etc. MATERIALS: Made in Korea, Aluminum casing and drum, steel cable LOAD CAPACITY: 110 - 132 lbs; STROKE: 59 inches; WEIGHT: 22.92 lbs Without an internal spring, the zero gravity balancer can support a heavier weight capacity than a normal balancer. When the operator releases the tool, it remains at the same position and will not fully retract.Overall, this useful tool increases worker efficiency and safety while decreasing worker fatigue.
