[RE-wrenches] rebar v/s fiber

[Kent Osterberg]

The need for rebar or not depends on how the pole is secured and on the 
shape of the footing.  If you are installing a pipe in a deep narrow 
hole per most mount manufacturer's specifications, no rebar should be 
necessary.  Anything else will certainly require rebar and per 
manufacturers' disclaimers should be designed by an engineer.  For 
example, if the installation will have j-bolts in the concrete with the 
post welded to a plate held in place by the j-bolts, a full rebar cage 
will needed.
