The EH Tapered drum compensates for changing spring rate.
Heavy-duty construction, tapered drum compensates for changing spring rate. Direct spring powered... No motors or expensive gear trains to break or wear out.
Series 'BH' Tapered Drum tool balancers keep tools within reach and reduce damage to tools by suspending them out of the way above the work surface. Risk of repetitive motion injury is reduced because only a light, downward force is required to place the tool in proper operating position. As the tool is lowered, and the spring is wound more tightly, the effective drum diameter increases to compensate for the increased force. Thus, when properly adjusted, the taper drum keeps the tool at the positioned height.
