AWS 502 is a reinforcement bar designed to enable safe lifting of heavy line-array systems. It functions as an accessory for WORK PRO WTS lifters and is compatible with WTS 1206, WTS 905, and WTS 708 models, providing a rigid link between the line-array and lifting points. The item supports secure load transfer during installation and service tasks; however, the product page does not publish dimensions, weight, materials, or load ratings.
