All Steel trailer jack caster!
Ever seen one of those cheap plastic jack wheels just fall apart when you roll your trailer?
Not this one! All steel wheel, with heavy duty swivel. Rolls Easily, and because it is all steel, the center won't break out when it is loaded heavy!
Pins on to all standard trailer jacks with 2" or small tube (I think that is ALL round tube jacks). Measures just over 2 inches inside, and the wheel is 6 inches.
It is A STEEL WHEEL (painted black, but steel!)
