The ZipWall ZDS ZipDoor Standard doorway dust containment kit is a great way to create a dust barrier when all you need to seal is the doorway. This kit only takes a minute to install and is ideal for jobs where doorways measure up to 3' x 7'. Will increase profitability on every job by dramatically cutting labor costs. This includes commercial jobs as well as residential kitchen remodeling, bath remodeling or renovations that will disturb lead paint. Kit makes it easy to meet the EPA's RRP requirement for a covered doorway. To attach the ZipDoor, ZipWall invented a very special double-sided tape. One side of the ZipWall tape is gentle on painted surfaces like traditional painter's tape. The other side was designed to hold plastic sheeting and lets you reposition the ZipDoor for up to an hour before fully bonding to the plastic. Made from 4 mil plastic sheeting and includes 2 pre-installed heavy-duty zippers that allow easy access through the doorway. ZipDoor zippers are glued-on for maximum strength and durability. A stitched-on zipper can fail if pulled sharply or tugged because the stitching creates a perforation. Barrier system sets up in minutes and adds a professional touch to the job site. No tape, no ladders, no damage. Use in commercial and residential remodeling settings, as well as in flood restoration, mold remediation and many other applications.
