This is a picture of a Bearing Buddyョ size gauge card being used to measure a dust cap.  It is a credit card size measuring tool that will measure your trailer's dust cap, to help you select the correct Bearing Buddyョ model.  It will measure the five most common size dust caps, which represents about 95% of all dust cap sizes.  The size gauge cards are available at marine dealers.  If your marine dealer does not have size gauge cards in stock, they can get them from their distributor.
