Drive Medical's Economy 4 Hook IV Pole with removable hooks is versatile and easy to use. With an easy push-pin release, it converts between a 2-hook and 4-hook top. (Product is available in 2-hook and 4-hook form.) Chrome-plated steel with a weighted base provides strength and durability while, most importantly, reducing the risk of tipping. A portable IV pole with a locking collar allows for simple height adjustment to the stem, and four rubber wheels ensure smooth transportation and maneuverability. Height range from 40 inches to 82 inches. Backed a limited lifetime warranty from Drive Medical, a leading brand of medical goods for more than 20 years, you can purchase with confidence
