Each swivel track wheel assembly comes with four track wheels (4-wheels) for maximum stability and each castor wheel has 360° swivel and locking mechanism. These wheels are not only full 360° swivel, but also able to freely slide within the wheel housing in any direction by an extra 1″. This means that the track can be as uneven as 2″ in places and still not effect the smooth operation.
