<-There is a
safety cable for the
right arm and a separate safety cable for the
instrument itself. This second safety for the instrument is not the best design, as you really have to squeeze, bend and thrash it to install it. >
This second safety, according to the Right Arm product manager, will slip right through the space provided on the Tilt Adjustment Arm when the bolt is backed out a few turns. This added space allows the safety to wiggle right through the space provided without having to use a hammer, Vice-Grips*, or other horrendous 'bang on it' type tool.
