This is an original Oster Pro part. The Front Spring Grip is used on the Oster Massager. The Grip is comprised of three spring and two clips. The Grip attaches to the massager with the two clips. It's common for the springs to stretch out over time. It is suggested to replace the front and Rear Grip (part number 041880-035-000) at the same time. No tools are needed to replace this part.
