A vertically adjustable, shock-absorbing mounting device for supporting an object comprises a foundation body including a metallic cover plate, and a support plate having an underside and a supporting surface for the object. The support plate includes a ledge protruding from the support at no more than two adjoining sides of the support plate for engaging and retaining the object on the supporting surface against rotation in relation thereto. A threaded spindle has an upper end connected with the underside of the support plate and a lower end connected with the cover plate, one of the spindle ends being in threaded connection and the other spindle end being in locking connection with the respective plate whereby rotation of the threaded spindle adjusts the spacing between the foundation and the support plate while the object is held against rotation by the retaining engagement with the ledge.
