Rated 4.5 out of 5 by 2 reviewers.
Rated 4 out of 5 by Glass Block Mortar Spacers work really well These little guys will allow a novice to install glass blocks like a pro. They insure uniformity in the mortar joints. My only problem was when I needed to break off the horizontal legs to use them as end of row spacers. The verticals have a weakened spot to allow them to snap off easily, the horizontals don't have that. I ended up cutting them off with diagonal cutters and smoothing them with a bench grinder. A little more work, but they all worked great in the end and the glass block window looks professional. These seem to me to be a little expensive for what they are, but it's the only game in town.

Rated 5 out of 5 by Without these spacers a motar glass block installation would be impossible This a handy package to have the option to be able to use For either size block and not be stuck with unusable parts for future projects January 8, 2013
