Make your own adjustable tapeless seal

The Slide™ extending adaptor is the innovative component of the FoamRail Span™ tapeless seal. It converts two FoamRail™ tapeless seals into an adjustable rail that can tightly seal up to 7 feet 6 inches of a dust barrier – with only one pole.

Note: The Slide™ extending adaptor also works with existing 3 foot and 5 foot FoamRail™ tapeless seals. It extends any two rails to nearly their combined length and requires only one pole.
