Not sure exactly, I know I can get a tempered 30x30x 3/8" for $50. For the adhesive I used the Loctite brand that's cures clear. Instead of and 8/32" screw for the ends I used a 1/16" roll pin ground it down near flush so that it would fit in the channel smoothly.

Here's on that I cleaned up today, the adhesive is pretty strong, but was easy to clean up
