The ZECA 633 is a tool balancer for any tool weighing 4.4-8.8 lb - for example compact drills, air screwdrivers, or small nutrunners - and works equally with any other tool or device in that weight range. It takes the tool's weight and retracts it clear of the work when released, so the operator isn't carrying it all shift.

Specifications:

• Capacity: 4.4-8.8 lb (2.0-4.0 kg), continuously adjustable
• Cable travel: 8.2 ft (2.5 m)
• Cable: stainless steel, 0.10 in (2.5 mm)
• Unit weight: 7.1 lb (3.2 kg)
• Die-cast aluminium case
• Anti-fall device standard: if the spring breaks, the load is caught rather than dropped
