The Crouse-Hinds V-Spring telescoping light pole from Eaton has a spring assist to offset the weight of the pole and light, enabling a worker to safely lower or raise the fixture. The pole is fully adjustable from 5 to 10 feet and travels vertically. It can be locked into any height position with pins or tethers. A 2-inch base is standard on all models. 866/764-5454; www.crouse-hinds.com.
