We have carefully designed and maintained the quality of our egg finger belts. Other companies have tried to imitate our specially formulated synthetic rubber “fingers”, but they do not hold up as well to wear and rodent attack. If you are not sure of the model number of your equipment, please measure the distance between the center of the drive shaft and the center of each idler shaft. If you have any questions about measuring, please call our toll free number 800-EGG-BELT.
