The ZipWall 20 poles are the tallest dust barrier poles. Anodized aluminum construction makes them sturdier than stainless steel, smoother to raise and to lock, and the best foundation for ZipWall accessories like FoamRail tapeless seals. These poles are versatile – extending from 5’2″ to 20′ – and built for heavy use. A 12 foot anodized aluminum pole is also available. The ZipWall 20 2-Pack is essential for jobs with high ceilings, and a great add-on to your existing set of ZipWall dust barrier poles. Two poles can be used to create a barrier up to 10 feet wide, or close off a hallway less than 10 feet wide.
