ZipWall’s spring-loaded, twist-locking poles are designed to make putting up a dust barrier easy and clean. With ZipWall spring-loaded poles you can build a dust barrier 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. These 20’ poles are made of high-quality anodized aluminum and provide you with maximum flexibility. Contains six units; each unit contains two 20' anodized aluminum spring-loaded poles with parts. They’re great when you’re working with very high ceilings, but because they collapse down to as low as 5’ 2” they work just as well with lower everyday ceilings. Plastic sheeting is not included.
