Abstract: A curling hack has a base made of a fire retardant plastic material and a replaceable grip pad with ends fixed to the top of the base. A mating groove and rib arrangement on the base and pad provide a resilient, cushioning effect. The grip pad is a soft, high friction material. The back of the hack is supported on the floor by adjustable height columns. The top surface of the hack is configured without a notch between the horizontal front surface and the upwardly sloping back surface.
