Trough cable tray is consists of a ventilated or solid bottom contained within longitudinal side members. Provides moderate ventilation with added cable support frequency and with the bottom configuration providing cable support every 4 inches.
Generally used with control and instrumentation cables in moderate heat generating applications with short to intermediate support spans of 5 feet to 12 feet. Trough cable tray bottom is available in flat sheet or corrugation that is 3 times stronger and 21 times stiffer than flat sheet bottoms. Corrugated seams between jointing sections eliminate need for bottom seam splices.
