Adjustable top plate device for a jack post

An adjustable top plate device for a jack post for supporting a top structure when positioned on a floor structure, the jack post having a telescoping rod and sleeve, the rod including a top plate and an opening extending therein, the adjustable top plate device comprising:

• a plate member defining a top surface for interfacing with the top structure and an opposite undersurface for engaging the top plate of the rod;
• at least one protrusion protruding from the top surface of the plate member for engaging the top structure, the at least one protrusion comprising deformable and resilient material;
• and
• an insert body extending beneath the undersurface of the plate member for being inserted in the opening of the rod,
• wherein the protrusion comprises a dome-like shape,
• wherein when the adjustable top plate device is mounted to the jack post, the insert body is inserted within the opening of the rod and the undersurface of the plate member engages the top plate of the rod.
