Abstract: A safety tie down assembly is adapted for use with pulling apparatus of the type used in the repair of collision damage to motor vehicles. The pulling apparatus includes a post carrying a power cylinder attached to a pulling chain which passes over a guide pulley on the post and then to the vehicle so that force applied to the piston in the cylinder applies a pulling force to the vehicle through the pulling chain. The pulling force is counteracted by a primary anchor chain coupled to the post and extending to a floor anchor. The safety tie down assembly comprises a rigid anchor guide and support removably placed in the floor anchor and contacted by the primary anchor chain so that the restraining force in the primary anchor chain is evenly distributed at the edge of the floor anchor to prevent damage to the floor. A safety anchor line is connected to a separate location on the post assembly and is then connected to a ring-like cable carried on the rigid anchor guide and support.
