Abstract: An improved yarn shipping rack that is modular in concept and includes an outer, skeletal frame having vertical and horizontal members united to form same is disclosed herein. Inner horizontal members in vertical alignment are secured to outer vertical members, and have yarn package receiving elements provided thereon that extend angularly outwardly therefrom. The yarn package receiving elements are preferably provided on both sides and are staggered or offset on each side with respect to each adjacent element to permit a greater number of yarn packages to be received in a given unit of space. Stacking means for the individual modules are provided at the upper and/or lower ends of same to receive the next adjacent module and hold same against appreciable lateral movement. A group of modules may thus be safely stacked during storage and/or transit. Channels or other means are provided on the lower end of each module to receive a lifting element such as a fork-lift or the like.
