Before choosing the duplex spring model please read the following: Duplex springs are not made by Technique and are attached post factory. Duplex springs, and all parts related to the USA made duplex spring connections, have no warranty. Duplex springs should not be bent beyond 45 degrees during use! Duplex springs can be damaged easily if operated beyond the 45 degree angle or during detaching the handpiece from the end of the flex shaft. Duplex springs can also fail during normal use. If you choose a duplex spring model, you may want to purchase additional inner duplex springs (Single piece part number 134.279 Foredom HP76-Pack of 12 part number 134.280 Foredom HP76B) and learn how to change out and replace the inner duplex spring, the most common part that can fail.
