<p>PURPOSE:To vary the angle of lacks freely and block the gaps at the coupling section by providing a plurality of coupling holes at coupling plates made at the ends of punching racks opposed to each other, and making a recess at one of the edges of the opposite coupling plates and a crooked hole at the other, and engaging them with each other. CONSTITUTION:A rack for laying a cable is constituted by coupling a plurality of punching racks P each in the shape of U shallow in section and each provided with a plurality holes P1. Band-shaped coupling plates 1 are made at the faces where the punching racks P are opposed to each other. For the coupling plate 1, a recess 3 is provided at one side of the edges in the longitudinal direction, and a crooked hole 4 is made at the other, and the recess 3 and the crooked hole 4 are engaged with each other. Hereby, the angle of the bending of the punching racks can be varied freely, and also the gap at the coupling section is blocked, and a kind of cable ceases to be seen from downside of the cable rack.</p> |
