Cable reels from United Equipment Accessories incorporate slip rings and can come with two, three or four conductors, depending on customer requirements, with up to 22 feet of extension capability. Reels have all-steel construction and a durable powder-coated finish with quality SOW cable that is flexible and weather-resistant. Top-half covers prevent snow and ice accumulation on coiled cable, preventing reel failures caused by freezing. Various mounting brackets and cable guides are available, and reels are available for both right- and left-hand wind for mounting on either side of the truck. They have an 8-inch-diameter footprint. 800/394-9986; www.uea-inc.com.
