Never damage another wall. With the ZipWall® Side Clamp and Foam Rail, you can create a tight seal without tape. The Side Clamp™ wall mount snaps onto the Foam Rail™ cross bar and then pushes the plastic against the wall to create a dust tight edge. It's a crazy looking tool but it's quick and easy to use. Take a look at the short video demos listed on this page, one shows the Side Clamp™ wall mount in action. Also, take a look at our Side Pack which includes Side Clamps™, Foam Rails™, and a Custom Bag.
