The patented PoleEnforcer® features a full length flange and continuous taper design that allows it to maintain contact with the pole butt below grade. Because of the PoleEnforcer's patented design, it is able to develop longitudinal strength ratings that far exceed any other steel reinforcement product available. PoleEnforcer units can reinforce poles that others consider rejects, saving utilities significant amounts of money versus changeouts.
