Abstract: A device and method for spanning a gap between adjacent surfaces is provided. The device includes a pin or pin plate rotatably connected to a cover plate, preferably using a ball and socket joint. The pin or pin plate, connected to the cover plate, can be inserted into the gap and the cover plate can be rotated to engage the adjacent surfaces, thereby covering the gap.
