The Cable Caster facilitates installation of lightweight, low-voltage wiring in ceiling, rafters, subfloors, and other hard-to-reach spaces. The handheld dart gun-like device enables the installer to fire an accurate dart up to 50 feet to the cable supply. Monofilament line attached to the dart is paid out from a takeup reel attached to the Cable Caster. The communications cable then is attached to the dart and reeled back to the installer. Darts are made of ABS plastic that glows in the dark. The unit includes a holder that accepts a pocket light or off-the-shelf flashlight, sold separately.
