Glass Setting Tape

Iv'e used this tape before but forgot how. Help?

 

Bend setting tape in half length wise. Insert into channel and firmly push the glass down in between the two halves. Light rapping with a rubber mallet on top of the glass will help to seat it firmly in the channel. Trim any excess with a razor blade even with the top of the channel after the glass is fully seated.
