Rated 3.8 out of 5 by 11 reviewers.
Rated 5.0 out of 5.0 by Installation is a breeze with these This made the whole project of creating a glass block wall in our shower a breeze. Make sure you cut the top piece in half so you can get the last row in. February 17, 2015
Rated 5.0 out of 5.0 by The product made my job so easy The tracking lined up my glass blocks perfectly. I used them to make an eight foot wall for my walk in shower. They also made it strong and sturdy. I had it up in no time. I'm a 60 year old woman that has never put up a glass block wall before. And this product made it very easy! June 4, 2013
Rated 3.0 out of 5.0 by Good intensions Before I used these I checked with the glass blocks I previously had ordered. The blocks may have been generic as they were a tad too tight to fit the channels. I returned the channels and installed the blocks without them. Be careful when ordering blocks and mounting hardware. December 9, 2012
Rated 4.0 out of 5.0 by Channel fits perfectly I only needed one, not 4, so it would be helpful if they could be purchased individually. Channels can pool water if the correct caulk is not used - especially at the bottom of the glass blocks. August 21, 2012
Rated 5.0 out of 5.0 by Thinline Perimeter Channels work really well I had no problem installing the perimeter channels, just stick close to the Pittsburgh Corning installation instructions and you won't go wrong. A lot easier than trying to mortar the blocks onto a wood frame. January 24, 2012
Rated 5.0 out of 5.0 by Good Product Got exactly what i thought I was getting. Easy to work with and fit snugly on the glass block panels that were installed in my stall shower. Material was strong, flexible and not brittle in any way. August 14, 2012
Rated 1.0 out of 5.0 by Thinline Channel As with many other reviews these channels do not fit "Thinline" blocks. I was using them in a wood frame and found that by splitting them in half with a razor knife and allowing about a 1/16 inch gap between the two halves they worked just fine. Had to add a few fastener holes. Be sure to caulk the blocks into the channel. The real point is that I shouldn't have to mess with them at all. May 23, 2014
Rated 5.0 out of 5.0 by Easy to order and if delivered to the store the shipping is free. Needed the item. It would be nice if The Home depot stocked thin line glass blocks and the thin line accessories. June 24, 2014
