    • Whereas pull lines are utilized for installing electric wires in electrical conduit between junction boxes by attaching a pull line to the open end of a high-speed line carrier closed by an elastomer molded bulb of specific dimensions relative to the type and size of conduit and in which the hollow core device is slightly smaller in diameter than the conduit through which it travels, said combination of hollow core and molded bulb fashioned to complementary conduit creating physical characteristics, including a frictionless seal, allowing same to travel through conduit at high speeds, measurable in feet per second with little resistance, in response to a vacuum created at opposing end of conduit, or in response to a driving force of air applied at insertion point of same, or in response to a combination of these means. Additionally, usage on larger scale applies to waste disposal networks with same results.
