The EWF Series is the "workhorse" of the ENDO line. They feature fully enclosed housing, fall-arrest device (auto-brake), and manual drum locks. If a spring breaks, the brake automatically locks to prevent tool damage. The manual drum lock keeps the drum from rotating to allow easy change out and maintenance of tools. Springs are enclosed in a replaceable cartridge for safe and easy repair. EWF Series Balancers are also available in an unpainted version. To order, add "NP" at the end of the standard "EWF" part number.

Choose a balancer rated for the exact weight of your tool/load. Never exceed rated capacity. We recommend selecting a model with a weight range where your tool falls in the middle of the capacity range.
