Molded rubber product. Above is a hinged lid made of elastic plastic. The whole product is covered with bumps, for a greater obstacle to sliding. At the ends are provided connectors of the "puzzle" type. The required length of the cable channel is dialed by connecting the desired number of elements.
It is laid on asphalt or on the floor. Elements are interconnected using a jigsaw puzzle connection. The design is stable due to its mass. If necessary, an anchor can be used.
