The invention relates to item mounting apparatuses, and particularly, to apparatus that may be secured to a ceiling surface for mounting an item to the ceiling. The apparatus has an upper support securable to a ceiling surface having an outwardly depending alignment member, and a hub having an item support structure with a through aperture and a securing mechanism for releasable securing of the hub to the alignment member. The hub is secured to the alignment member, when the alignment member is inserted through the through aperture of the hub, through use of the securing mechanism. The securing mechanism may have a shaft collar with a spring loaded release mechanism. In one embodiment, the item support structure has a wheel support assembly having means for engaging a wheel and an outwardly extending hollow shaft, the hollow shaft configured for insertion in a centerbore of the wheel and for guiding the hub along the alignment member when mounting the wheel to the ceiling.
