ZipWall has introduced the self-closing Magnetic Door Kit 3070 for commercial steel-frame doors. The Magnetic Door Kit 3070 covers a standard 3- by 7-foot commercial doorway and keeps dust contained during interior renovation and remodeling projects. Installation is literally a snap with magnetic strips that attach the door panel to the steel frame. Powerful self-closing magnets provide workers easy, hands-free access to the job site and maintain the dust seal. The flame retardant door panel features a clear plastic window and a clear pocket for documents. This door is reusable, durable and easily handles high traffic.
