Rated 5.0 out of 5.0 by parmodels The Provantage system makes building a glass block wall a breeze
The complete Provantage system for constructing glass block walls is a great alternative to the traditional use of mortar to set the blocks. The horizontal spacers are part of the system and do a very good job of establishing the correct vertical spacing of each block row. They are easy to use and do the intended job.

Only need 1.5 out of the 4 pack. Unfortunately not sold as singles. This added to overall cost of project.

Made a small, interior glass wall. The horizontal spacers helped both in keeping lines true and in stabilizing the wall.
