The Kelley FF Series FLEXFRAME® loading dock shelter accommodates a wide variety of vehicle sizes and types, while providing full trailer access during the loading process. A gravity-biased, flexible frame yields to misguided vehicles, preventing costly building and shelter damage. As the vehicle approaches, if off-center vehicle contact occurs, the dock shelter moves up and back to prevent costly damage to the wall and shelter. After the vehicle leaves, a gravity-biased design returns the frame to its original position.
