ABSTRACT:
At a truck loading dock, a flexible draft shield helps seal a lower inner corner of a dock shelter. Instead of a foam core, the draft shield includes a resiliently flexible frame that supports a pliable cover. In some embodiments, the frame includes a spring steel loop that is able to flex upon being squeezed between two members of the dock shelter. In some cases, the draft shield is hollow and open at the bottom.
