A telescoping lever arm comprises a tube and a rod. The tube has an opening at one end thereof and has an inner circumferential dimension along the inside thereof. The opening is smaller than the inner circumferential dimension of the tube. The rod has an outer circumferential dimension that is smaller than that of the tube's opening. The rod resides partially in the tube and extends therefrom via the tube's opening. At least one annular flange is coupled to the rod at a portion thereof residing in the tube. Each such annular flange is defined by a circumferential dimension that is larger than that of the tube's opening and smaller than the inner circumferential dimension of the tube.
