Parallel action jaws excel for adjusting temples, barrel and front piece on any eyewear style or frame material. Conventional pliers with scissor closing action can pinch thicker materials and mar the frame. Parallel Jaw End Piece Pliers feature long, comfortable foam covered grips and narrow jaws that fit comfortably in tight areas. The Tri-Angling Plier is the perfect tool for adjusting nylon cord rimless or any fine metal endpiece. Manipulate temples without putting pressure on the eyewire, endpiece or lens. Use a piece of cellophane tape to protect frame surfaces and then safely bring temples in or out without stressing the frame. The 5119 is an excellent tool for making adjustments to delicate corners.
