Zipwall 10 spring-loaded dust barrier poles are strong and lightweight, telescope up to 10 ft high and twist to lock. They are an ideal dust protection solution for residential remodeling, renovation and repair work. Contractors and DIY home owners alike find these poles easy to use, easy to store and a significant time saver. Each spring-loaded pole takes seconds to set up without a ladder. The innovative non-skid, non-marking head locks the barrier material onto the pole, allowing it to be raised with the pole and holds it securely in place without damaging the ceiling. A tight dust barrier can be set up in just a few minutes, one pole at a time, without ladders, tape or damage. The 2-pack is a great add-on for an existing Zipwall dust barrier system. Two poles can also be used to seal off a hallway or a small room less than 10 ft wide.
