It is extremely difficult to fit replacement plastic temples to existing frames.
We have many thousands of plastic temples. However, eyeglass makers design unique temples for each frame they produce. Generally there are a dozen or so basic styles. The image below shows the hinge area of three temples. Note that the number of barrels through which the temple screw passes can vary from one to five. The thickness of the barrel also varies. Finally, the angle at which the hinge barrels are attached vary. Take a close look at the images.
Some of the factors that determine replacement temple fit are color, number of barrels, angle of barrels, and thickness of barrel. In addition, some temple ends are cut at a 45 degree angle while others are cut at a 90 degree angle. Finally, Temple width and temple length must match the original.
Fitting plastic temples is nearly impossible unless we have the original frames in hand. Even with the original frames, we can make a match about 65 percent of the time.
If you ship your frames to us, have the lenses removed or buy enough insurance to cover the lenses should the package become lost. You may send just the broken temple if you include both pieces. We specialiaze in vintage out of production frames. Most of our plastic frames date between 1955 and 1985. If your frames are newer, we are seldom able to help. Please call 207-872-5849 and talk to us before shipping your frames or a temple to us for replacement purposes.
