ABSTRACT:
A pulling tool is used for pulling an object relative to a support. The pulling tool includes a pole having means at one end for engaging an object to be pulled. A stop is affixed at a selected position on the pole. A threaded, rotatable sleeve loosely or slidably receives the pole and has one end for abutment with the stop and another end from which the engaging means projects. An annular member threadedly engages the exterior of the sleeve to allow movement of the sleeve axially of the annular member upon rotation of the sleeve. A stand-off means is coupled to the annular member for engaging the support while the object is being pulled, and there is a handle for turning the sleeve to retract the sleeve and the pole relative to the fixed support.
