Claim 9:
10. A puller system that pulls one of a string or wire behind a wall, comprising:
a weight; and
a body, wherein a hollow cavity in the body is configured to receive the weight,
wherein the body is oriented in a substantially vertical position behind the wall, a material within the wall resists downward movement of the puller system,
wherein in response to drawing the weight upward through the body and then releasing the weight, the weight travels downward towards the distal end of the body, and
wherein a distal end of the released downward travelling weight impacts the tip at the distal end of the body such that momentum of the downward travelling weight is transferred to the tip thereby driving the body downward through the material behind the wall.
