The ENDO EWF-15 is a zero-gravity spring balancer for any tool weighing 20-33 lb - for example larger nutrunners, angle drills, or pulse tools - and works equally with any other tool or device in that weight range. It holds the load weightless at any point in its 4.3 ft of cable travel.

Specifications:

• Capacity: 20-33 lb (9.0-15.0 kg)
• Factory-set load: 26.5 lb (12 kg)
• Cable travel: 4.3 ft (1.3 m)
• Wire rope: carbon steel, 0.16 in (4.0 mm)
• Unit weight: approx. 8.4 lb (3.8 kg)
• Fall-arrest device standard: if the spring ruptures, a safety pin stops the tool from falling anywhere in the cable travel

Lighter tool? See the EWF-9 (10-20 lb). Heavier? Continue with the EWF-22 (33-49 lb). Need more reach? The ELF-15 is the 8.2 ft long-reach version.
