Light duty chain used to suspend lead-lined medical curtains from wall-mount or ceiling mount tracks. Made of zinc-plated steel from a 1/8"diameter solid steel wire. Links formed into a figure eight, then twisted into a 90° angle so it won't spin or jostle.
Chain can be cut to exact length on site during installation so the curtain hangs exactly at the right height (1" floor clearance} regardless of location of mounting track.
