Abstract: A tensioning assembly for a door system, which includes an upwardly acting door supported by a frame and connected to a counterbalance system having a counterbalance spring, the tensioning assembly including a rotatable tension plate coupled to the counterbalance spring and rotatable relative to the counterbalance spring, the tension plate being selectively moveable between a disengaged position where the tension plate is freely rotatable and an engaged position where the tension plate is rotationally fixed to the frame; and a spring adapted to urge the tension plate toward the engaged position, whereby when in the disengaged position the tension plate is rotatable to adjust tension in the counterbalance spring and the tension plate is returned to the engaged position to maintain the tension.
