ZipWall® spring-loaded, twist-locking poles are designed to make putting up a dust barrier easy and clean. Using these poles you can build a dust barrier up to 20' high and as wide as needed in just a few minutes. Their telescoping action lets one person set up a barrier from floor to ceiling without tape, ladders or damage. The innovative head and plate design makes it easy to attach plastic sheeting (up to 8 mils) or ZipFast™ Reusable Barrier Panels. Place poles 10' to 12' apart or closer if there is significant air movement.
