Ni Ti Open Coil Springs
Ni Ti super elastic open coil spring comes in standard lengths of 7 inches and can be deflected to twice their original length without causing any permanent deformation. They provide constant force for maximum efficiency in opening spaces when springs are used to create spaces between teeth or, more simply,to move points away from one another. The coils are compressed when loaded and provide forces outward to create and maintain needed space.laced on wire compressed between two brackets.
