Abstract: An indoor golf hole having a canister adjustably supporting a golf cup. The canister is engageable by use of a collar for supporting it to a subflooring in a room. A thread engagement between the collar and canister can provide means for vertically adjusting the height of the canister to accommodate different carpeting thicknesses. Alternately, interior adjustment mechanism may be provided within the canister to independently adjust the golf cup elevation. In other forms of the invention, the canister may be provided to be inserted within a cored hole in a poured concrete floor and embedded in hydraulic cement. In the concrete floor installation modes, the golf cup is supported and adjustable by means of a movable disk thread-adjustably supported within the canister for adjusting the height of the golf cup relative thereto. The canister may have a thread-engageable double-walled construction, or alternatively a cap with a threaded boss for thread-engaging a machine-type screw carrying the disk.
