I got 1/4" tempered glass, $40 a side here. You can reach the channels fine through the big hole but it's hard to reach down low. I used black weatherstrip adhesive to glue the strip into the track. When cutting the template, cut on the line but don't assume it's an exact fit. I highly recommend doing a test fit with masonite before getting the glass cut and take that as a template rather than the paper. To make mine fit right with no gaps I had to tweak the template a bit. I also had to move the front track forward a little farther forward at the bottom than stated to get it to roll up and down right. Also, I only used half of it, and I still have half the piece left over from lengthening the track if anyone needs it.
