An apparatus includes a frame having a drive shaft mounting portion, a power tool restraint portion, and an adjustable forearm portion, wherein the power tool restraint portion is adapted to register a portable rotary power tool with the frame. A drive shaft is mounted with the frame in the drive shaft mounting portion, wherein the drive shaft is sized to be coupled with a rotary output of the power tool. A mounting bracket having arms ending in angled arm ends to facilitate the use of the apparatus in confined spaces is adjustably mounted to the forearm portion. An adapter set includes at least two adapters of differing sizes that may be removably attached to the mounting bracket and used to supply a force to the structure through which the line is being pulled that opposes the force on the structure produced by the line itself, thus stabilizing the structure.
