A rail assembly has at least two hangers, a base and a rail body. Each hanger is a straight slot and has a narrow side and a clamp side longitudinal forming on the hanger. The clamp side is wider than the narrow side. The base has a base body and at least two mounting troughs. The mounting troughs are securely mounted on the base body and each mounting trough corresponds to and is slidably mounted on one of the hangers. The rail body is mounted on the base body. It is only to hang the assembled rail body with the base onto the hangers for assembling the rail assembly without using any tool, so to assemble the rail assembly is easy and convenient.
