A radius in a cable support fitting is the size of an arc or bend. The aluminum I-beam design of ITray is perfect for industrial installations with large diameter cables in long span situations, minimizing total tray width and creating a smooth transition between straight sections and fittings. A structural offset in the sidewall creates strong, mid span splices. Standard 12", 24" and 36" radius are available for all fittings. Class 1: Designed for use with NEMA Classes 12B and 12C cable trays. These systems have 1 1/8" wide side rail flanges and 4-hole splice plates. A smaller radius. In practice, cable tray dimensions are a system of interrelated measurements โwidth, depth, length, and material thicknessโthat directly affect cable fill compliance, heat dissipation, structural loading, and long-term expandability.
