System and method for garage door counterbalance

A tool for use in installing an energy storage device for a counterbalance system, the tool comprising:

• a threaded shaft having a proximal end and a distal end;
• an engagement member attached to the threaded shaft at the proximal end, the engagement member having an exposed proximal face and the face defining an elongated engagement cavity;
• a locking nut disposed on the threaded shaft between the engagement member and the threaded shaft distal end;
• and
• a bearing member fixed to the threaded shaft between the locking nut and the engagement member, the bearing member being rotatable with the threaded shaft;
• wherein the engagement member and the threaded shaft are positioned to be co-axial with the slidable carriage;
• wherein the elongated engagement cavity extends radially from the center of the engagement member in two directions;
• wherein rotation of the locking nut may be a prohibited such that a position of the engagement member relative to the locking nut is adjustable by rotation of the threaded shaft distal end.
