The Spectrum™ pins are designed and manufactured to an exact tolerance. The pin leg dimensions of all three pins are .016 x .018 to be easily inserted into the Spectrum™ vertical slot of .020 x .020. With the exact tolerance of the stamped pin, the possibility of rotation of the pin in the bracket slot is eliminated.
The 1st and 2nd stage pin is designed to fit securely into the bracket, allowing for free sliding mechanics of the archwire. The 3rd stage pin is designed to fit into the vertical slot of the bracket while holding the archwire securely in place. The Tandem pin is designed to hold the archwire securely in position while offering the addition of a hook for surgery cases or vertical “cross” and class II elastics.
