The Creep-Zit Fiberglass Wire Running Kit (Green) from Labor Saving Devices includes five 4/25-in. dia x 6 ft. green fiberglass rods and is used to fish insulated wall, noninsulated walls and between carpet tack and wall. The eggbeater-shaped head whisk is designed to be used as a guide to keep the rods from getting hung up on obstacles and to provide a means to creep side to side when turning rods with your hands. The rods retain their memory to go straight wherever you want them to go.
