Abstract: A one-piece rubber or elastomeric block has a relatively hard or rigid base portion and a relatively soft or compliant ledge portion. The base prevents a windshield from sliding downward as it is being bonded to a window frame of a vehicle and the ledge serves as a compliant cushion which prevents the weight of the windshield from extruding a soft bead of urethane or other sealer from between the windshield and the frame. The elastomeric block sits within a channel of a vehicle window frame. A windshield is mounted upon the vehicle window frame, resting upon the elastomeric block and attached to the frame via the bead of urethane.
