Barwalt Hollow Leave-In Tile Spacers

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.
