Model Stand Detail Photo - Casters  
Mounted on the side of the model stand are four 2" swivel casters enabling the unit to be tipped vertically and rolled from place to place or through doorways or from room to room. 

An optional set of four  3" heavy-duty swivel casters can be purchased as an accessory (factory installed). 

These 'Landing Gear Casters' can be deployed to let the model stand be slightly elevated off the floor. Thus a very slight horizontal force will glide the unit from place to place or allow rotation about its axis in a kind of 'lazy-susan' motion.
