The ZipWall ZDC ZipDoor Commercial Doorway Dust Containment Kit is a great way to create a dust barrier when all you need to seal is the doorway. This kit installs in under a minute and is ideal for commercial renovations, hotels, hospitals, etc. It will increase profitability on every job by dramatically cutting labor costs. The ZDC ZipDoor kit was designed for commercial doors (up to 4-Feet by 8-Feet). It also 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 flame-retardant plastic sheeting, the ZipDoor kit has two heavy-duty zippers pre-installed to allow easy access through the doorway. The 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. Contractors across all industries have given our products an enthusiastic thumbs-up. Our barrier system sets up in minutes and adds a professional touch to the job site.
