EZ-ier Zippers have an innovative design that prevents the inner puller from swinging and getting stuck in between the Zipper and Plastic Sheeting, thus diminishing the likelihood of a jammed puller. This unique feature saves you time and frustration while providing a smooth glide and protecting the integrity of your containment. EZ-ier Zippers are designed for use with Containments or Dust Barriers for Disaster Restoration, Remediation, Abatement, Renovations, Remodeling, Greenhouses, Boat Shrink Wrap and more! Use EZ-ier Zippers with our EZ-ier Tape for an air-tight containment that is tough enough to withstand negative pressure yet removes cleanly! Sold as individual two-packs and cases of 12 two-packs.
