A rail assembly may include a housing with a cavity and a channel in the cavity. A cam may be disposed in the channel. The cam may include an elongated portion. One or more locks may be disposed in the channel and contact an outer surface of the cam. When the cam is rotated from the open position, the position of the locks may be adjusted to retain a panel disposed in the rail assembly. When the cam is rotated from the closed position to the open position, the position of the locks may be returned to the initial position and the panel may be moved and/or removed.
