Continuous forces to close or maintain space!
•   Made of premium Nickel Titanium wire
•   Provide continuous forces throughout activation
•   Virtually no permanent deformation with proper usage
•    Recommended activation length is two times original spring lenth
•   The tooth moving force of Variable Force Springs gradually decreases over the activation range
•   The tooth moving force of Supperelastic Force Springs remains near constant over the activation range
•    Variable Force: 6mm, 9mm, 12mm, 15mm
•    Superelastic Force: supper light, light, medium, heavy
•    7 inch lengths (3 per tube)
•    15 inch per spool
 
Helpful Hint:
•   The greater the wire size, the higher the force
•   The smaller the inside diameter, the higher the force
•   The shorter the length, the higher the force
