Barwalt Hollow Leave-In Spacers * The first industry approved Hollow Spacer to be left in! * Years of research led to a spacer that would react like a rubber spacer but be hollow, thus allowing it to stay in the joint and be grouted over. Now the installer can grout a day earlier and not have to come back to remove the spacers before grouting. The Hollow Spacers will adjust on 10% and not compress further and these spacers are longer to handle the radius corner tiles.
