Drop chains are often used with privacy cubicle curtains to provide clearance for sprinkler systems to provide full coverage in the event of a fire. Using drop chains is an alternative to adding mesh to the top of the cubicle curtains to meet fire code requirements in many areas. In addition, drop chains can bridge the gap between a curtain and the curtain track system that may be mounted higher than the height of the curtain. Connectors are utilized to set a maximum spacing between curtain carriers. For taller curtains, the use of connectors directly between the carriers helps make it easier to open and close the hand drawn curtains. Curtain-Tracks.com offers common lengths, but can also customize lengths to meet your exact needs.
