The Smart-Wall kit, from Mr.LongArm Inc., is an easy-to-install temporary barrier that protects furniture and other items from dust and paint. The kit includes four 4-12 foot, three-section Twist-Lok legs and two 9' x 12' one-mil plastic drop cloths. Each leg has a swivel head that allows it to be used on flat or angled ceilings. The drop cloth is held in place at the head with a snap-on plate that has a layer of foam rubber that protects the ceiling and prevents slipping at the top. The legs easily adjust using the Twist-Lok extension and rubber feet prevent slipping at the bottom.
