Apparatus and method for installing wire behind existing walls

A puller system that pulls one of a string or wire behind a wall, comprising:

• a weight;
• wherein the weight is cylindrical,
• wherein the cylindrical weight is defined by an outside diameter, and
• wherein the cylindrical weight is defined by a first length;
• and
• a body,
• wherein the body is tubular with a hollow cavity,
• wherein the hollow cavity of the tubular body is defined by an inside diameter that is greater than the outside diameter of the cylindrical weight;
• wherein a distal end of the tubular body includes a tip that is configured to penetrate a material that is behind the wall,
• wherein the tubular body is defined by a second length that is greater than the first length of the cylindrical weight, and
• wherein a proximal end of the tubular body is configured to slidably receive the cylindrical weight,
• wherein the tubular body is oriented in a substantially vertical position behind the wall,
• wherein in response to drawing the cylindrical weight upward through the tubular body and then releasing the cylindrical weight, the cylindrical weight travels downward towards the distal end of the tubular body because gravity pulls the cylindrical weight downward towards the distal end of the tubular body, and
• wherein a distal end of the released downward travelling cylindrical weight impacts the tip at the distal end of the tubular body such that momentum of the downward travelling cylindrical weight is transferred to the tip thereby driving the tubular body downward behind the wall.
