Yes, and I am sad to say that it has been about 20 years since I had to
occupy myself with such things.  All I can pass on is what I thought of then:
vectors and impulse forces being what they are, can cause the tether to experience
forces FAR exceeding the weight of a child.  In mounting it, keep the tether
as horizontal and as well anchored as humanly possible.
