The PRS system features the patented design of the PoleEnforcer system that allows it to reinforce & reclassify wood, concrete, and steel poles up to three or more classes. Reclassifying existing poles saves significant amounts of money versus structure changeouts. The PRS system consists of a driven lower unit and upper units that are either bolted or banded to the pole.
Engineered wood, as a structural material, has the least "cradle to grave" impact on the environment when compared to concrete & steel.
