The fiberglass green and luminous push/pull rods have a bullet shape tip with cross hole (bullnose) on both ends, and, unlike the GloRod wire pushers, these can be used to pull wire as well. The luminous rods are made of phosphorous epoxy fiberglass truly glowing in the dark after being 'charged' in full light. The epoxy fiberglass makes them stronger than the regular 'green' rods, therefore a little stiffer.
