LIFELINE TENSION (2022-12-02)
Q1: What does “total deflection caused by the force straight down and straight up must not exceed 8 inches” mean?
A1: It means the deflection from a straight line between the stanchions exit holes must not exceed 4 inches up and 4 inches down for a total of 8 inches.  In practice, the deflection up is assumed to be the same as the deflection down and the downward deflection is measured.  When a force of 11.2 lbs (5 kg) of tension is applied, the deflection from a straight line between the stanchions exit holes must be less than or equal to 4 inches.
