**Previous versions of the mounting kit used a steel mount tube that is heavier by 0.14 lbs than
the weights listed in this table. The steel mount tube has welded mounting tabs and a constant
wall thickness. The currently used aluminum mount tube has machined mounting tabs and the
wall thickness is greater at the upper end vs. the lower end. Add 0.14 lbs to listed weights when
using the steel mounting tube.
