Orthoform NiTi Closed Coil Springs, 9mm. Pk 10

Nickel Titanium closed coil (tension) springs make closing spaces easier and provide a light, continuous force throughout activation. The super elastic springs are easily attached with the integrated stainless steel eyelets.

 IMPORTANT: We do not recommend expanding the 9mm coil spring to more than 21mm total length from eyelet to eyelet, or twisting more than 180° (half a turn). Any further expansion or twisting beyond these suggested limits may cause permanent deformation and affect force values.
