For repairing and rebuilding of Century and Franklin pump motors. With the Pool Tool Armature Holding Tool you can hold old style Century and Franklin armatures in place for impeller removal. Unlike a screwdriver, this inexpensive tool is machined to precisely fit the slotted end of the armature so it will not slip out and strip the slot. This tool fits a 1/2” socket wrench for excellent leverage to remove even the most stubborn impellers.
