The ENDO ELF-9 is a long-stroke spring balancer for hand tools in the 11–20 lb range — nutrunners, drills, grinders — where a standard 4.3 ft stroke is not enough reach. The 8.2 ft cable travel covers full work envelopes on assembly stations and line-side work.

The ELF series combines the EWF mechanism with a long cable, a manual drum lock for easy tool change-out, and a fully enclosed casing that eliminates pinch points.
