Barwalt Hollow Leave-In Tile 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, so it will 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.
Note: The 1/16" size granite spacer is not hollow and therefore must be removed prior to grouting.
