The Allied Bolt Polyethylene U-Guard (vendor part 9001-610, Millennium part 529255) measures 6 in x 10 ft and shields riser cable and drop wire running up a utility pole from mechanical damage and vehicle strikes. Its angled, slotted flanges let the guard flex with temperature swings instead of cracking, and the ribbed face adds impact strength for both hot summers and hard freezes. Lightweight polyethylene construction makes it fast for one-person crews to cut, fit and mount on pole risers during aerial builds. Millennium also carries matching U-Guard adapters, straps and lag screws to complete the pole protection assembly.
