Tightly seals a ZipWall® dust barrier in seconds without tape, ladders, or damage

The FoamRail Span™ Mini can seal up to 4 feet of a barrier with one pole. Extending from 2 feet 3 inches up to 4 feet, this adjustable tapeless seal is designed to fit in narrow spaces like hallways, be used around columns, or close the gap when a short segment is needed to complete the seal of a dust barrier. It snaps onto any ZipWall® pole and presses the barrier against the ceiling. Add Floor Adaptors to seal at the floor.

Also available in a larger version.

FoamRail™ tapeless seals prevent dust from escaping the work area during remodeling, renovation and repair.

Extend the Span™ Mini and flip the red tab to lock it at the desired width. IMPORTANT: Notice the arrows on the red slide – the direction of extending the Span™ Mini is essential to its proper function.

To seal a dust barrier at the ceiling, snap the Span™ Mini onto the ball joint of a ZipWall® pole, raise the pole with the attached Span™ to the ceiling, and lock it into place.

To seal a dust barrier at the floor, use Floor Adaptors. Replace the foot of the pole with a Floor Adaptor, place the Span™ on the floor, snap the pole onto it and set up the pole. Note: A barrier can be sealed at the ceiling and floor simultaneously with one pole.
