The 4 Pack Plus is a great package to start out with. It comes with four poles, enough to build a barrier in many configurations, plus 2 Foam Rail™ cross bars to seal straight across the ceiling without marring it. It also comes with a Carry Bag large enough to accommodate up to eight more poles or Foam Rails. If you are a contractor, keep a 4 pack plus in each truck so there will always ZipWall® system on the job. If you are a home owner keep a 4-pack-plus on hand for those messy projects.
The 4 Pack Plus also comes with two ZipWall® Standard Zippers. This zipper is great for interior work in temperatures above 55 degrees, and it's easy to install. The Standard Zipper makes getting in and out of the work area a cinch.
