This illustration clearly highlights the different behavior of the spring mechanisms during operation:

• In Mechanism 1 (traditional system) the springs are rigidly attached to the fixed caps at the ends of the shaft.
  In this system the springs helically twist and snake while winding or unwinding, causing obvious problems of friction and wear between the coils as well as between the coils and the central shaft.

• In Mechanism 2 (SURE-SPRING^® system) the springs are attached to a special moving cap, which slides lengthwise while winding and unwinding, keeping the spring coils packed and concentric at all times.
  This spring configuration avoids most of the wear mentioned above, allowing better performance and a much longer operating life-span for the spring mechanism.
