Abstract: A chain retention device includes a track member configured to be mounted on an external surface of a vehicle. The track member includes at least two guide surfaces which extend along the track member and a first set of rollers mounted on the track member between the at least two guide surfaces. The chain retention device also includes an elongated arm including a second set of rollers and one or more chain support surfaces. The elongated arm is positioned between the at least two guide surfaces such that the second set of rollers is in contact with the track member, and the first set of rollers is in contact with the elongated arm.
