The Rocker can be fitted to the rope at any point. It can be used hands-free, when travelling up and down the rope. The Rocker has been designed for use without a Shock-absorber.

The Rocker can also be used as a Rope Adjuster on a Work Positioning Lanyard or Flip-line (in accordance with EN358).

The Rocker is a self-tailing device, but the Thumb-catch can be used to park the device on the rope, for Work Positioning or use as a Rope Access back-up device. The Rocker is fitted with non-aggressive 'rope friendly' cam faces.
