A slider rail assembly includes a rail member and a bracket. The bracket and the rail member can be displaced with respect to each other. One of the rail member and the bracket is provided with a blocking feature, and the other of the rail member and the bracket is provided with a locking device. When the bracket is at a predetermined position with respect to the rail member and the locking device is in a locking state, the locking device blocks and is blocked by the blocking feature to prevent the bracket from being displaced from the predetermined position in a certain direction.
