Hey Ronald. We don't have a basic dust cap but If your trailer's hubs have a hub bore of 2.25", then I recommend the Bearing Buddy Bearing Protectors item # BB2240. These are designed for a 2.24 hub bore commonly found on 5,200 lbs axles. They will securely fit a 2.25" hub bore as well.

The Bearing Buddy Bearing Protectors item # BB2240 have a built in greaseable fitting that will keep your bearings lubricated. They also do a great job of keeping water and dirt out of your hubs and bearings.

What kind of trailer do you have and how did you measure your hub bore? It's best to use a digital calipers like item # PTW80157 to get the most accurate measurement.
