In replacing the drip pan of an ice box or refrigerator it is often necessary to bend over in locating it under the drip pipe. This trouble may be done away with by fastening two strips of wood in a V-shape to the floor beneath the refrigerator. When the pan is shoved under, it will strike one strip and slide along until it strikes the other. Then the pan is sure to be under the drip pipe. - Contributed by Lloyd A. Phelan, Beachmont, Mass.
