PURPOSE: A cable tray supported apparatus is provided to allow a channel to be hung by only a connection part above it, so there is no need to punch or form a skew form to hang the channel. CONSTITUTION: A cable tray supported apparatus is composed of a clamp(20), a screw(40), a joint nut(30), and a channel. The clamp includes an upper plate(21) and a lower plate(25), and a penetration hole(22) is punched at the center of the upper plate. The active ball(23) is punched at the both sides of the penetration hole of the upper plate. A screw hole(26) is formed at the center of the lower plate, and a vertical rod(27) is erected on the both sides of the screw hole of the lower plate. The vertical rod is penetrated through the active ball of the upper plate lower plate so that upper plate and lower plate are combined to be separated from each other. |
