Do I install an anchor on the top of the very last row?

The wall plan is supported on the bottom and on one side. The opposite side has the rounded off block. The top does not go all the way to the ceiling.
Asked by: Doug
There will be an anchor below the top row, but not above the top row.

Where do I need channels?

I am installing a shower wall attached on two sides one vertical and a horizontal bottom. Do I use channel on both? or just the bottom and brackets on the vertical?
Asked by: Kaneka
There are two ways to anchor glass blocks. Channel OR anchors. Channels are used when building a panel that is attached ar all four sides (like a window). Anchors are used when you are building a panel that has angles in it or is attached at two, three or four sides. For your installation, you will use the anchors. No channels.

installing in a shower area and when i get to the top where it is going to be open do i need to install the track on top?

also in interior installs like in video he doesn't use the anchors... Do I need them?
Asked by: DIYman
There are two ways to anchor glass blocks. Anchors or Channel. The ProVantage I Installation uses channel. Channel is used for straight panels attached to all four sides. Anchors are used for straight or 90 degree angled walls attached to two, three or four sides.Your project will use anchors. You can finish the top course off with a bed of grout, sealing all of the joints. Or, you could cut pieces of ceramic tile, glass tile etc. to the size/shape of the ends of the blocks and attach those. If your wall is straight and uses all 8x8" blocks, you could finish off your wall with End Blocks up the side and across the top with an Encurve at the conrer.

ProVantage Glass Block Anchors (5-Pack) is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from Glass block anchors Seem to do the job and helped make it easy to build glass block wall
Date published: 2016-08-09
Rated 5 out of 5 by from This product makes it very eassy to install the glass blocks. It holds the blocks stady, and in place while other blocks are placed, and assures that glass blocks don't fall out of alligment or come off, while the glass sealant is drying.
