A long, thin mechanism that must not be bent or twisted needs special care. We recommend that it be bagged (to keep it clean) and then to be buried deep in loose fill, in a box several inches larger on all sides.
It should not be tossed into an empty box that isn't long enough to fit it and handed
to the driver. Pulleys break, rods bend, frames twist, and let's not even go into how the sharp corners can cut
their way right out of a box. Because, frankly, this box is in such bad shape the corner was probably open already.
