Abstract: A shipping container for hanging parts, such as glass run channels, has a frame and separator assembly that hangs the parts slidably with a minimal thickness hanging and slidable separator between each adjacent part pair. Therefore, the shipping density can be made very high without mutual part damage, and the parts slide to their own shipping position. Packing and unpacking of parts is easier, since there are not precut slots or grooves into which the parts must be seated. In addition, since the frame and separator assembly are completely reusable, the surrounding sleeve can be economically made robust.
