Abstract: A profiled rail system (1) is used for bridging expansion joints or openings and or as edging of floor coverings (5). The profiled rail system (1) has a first (2) and a second profiled rail (3) which have mutually overlapping cover legs (6) being directed towards one another and oriented substantially parallel to the floor covering (5). The profiled rails (2, 3) can be displaced with each other. The first profiled rail (2) has a base leg (8) which, together with a cover leg (6) of the first profiled rail (2) forms a pocket (12) for receiving a leg (6, 8) of the second profiled rail (3). A first stop (10) is provided on the base leg (8) of the first profiled rail (2). The first stop (10) is an operative connection with a second stop (11) and the second profiled rail (3). The stops (10, 11) limit mutual displacement of the first profiled rail (2) with respect to the second profiled rail (3) in an expansion position.
