Abstract: The present invention provides a lever assembly for reversibly inserting a control device into a cell of a center for controlling electrical service. The center has electrical terminals and a post extending perpendicularly into the cell and the control device has a frame of cross-members. The assembly includes a left hand lever, a right hand lever, and a fastener adapted to secure the levers to one of the cross-members and position the levers to engage the post as the device is inserted into the cell. Each lever includes a pivot hole positioned towards one end of the lever. The pivot holes receive the fastener and allow rotation of each lever about the fastener. Each lever also includes an open-ended slot to engage the post in the control center. Each lever also includes means for manually rotating the lever about the pivot hole. The rotating means connects to the end of each lever opposite the open end of the slot.
