A device for lifting the legs of a display case in a store or office which is supported on legs. The device features a a “U” shaped frame, having a horizontal portion and two substantially vertical side portions extending from the horizontal portion. A face plate is engageable with a leg lifting component. A jack situated on top of the horizontal portion provides the lift for the leg lifting component. The leg lifting components may be adapted to any type of leg and engaged with the device allowing one lifting apparatus to engage any type of leg on any display case it is adapted to engage. The jack can be user supplied or included with the device as a unit. An optional skate for the lifted leg can also be provided.
