Bed Rails may be used as an assistive device or for fall prevention for individuals utilizing a medical homecare bed. Half rails 15021BV-LW are designed to be used with Drive's Lightweight Bariatric homecare bed series (Models # 15300LW, 15302LW, and 15303LW). Use of these rails with any other bed system is not recommended. With a limited lifetime warranty, the bariatric bed rails ensure patients are always supported.
