Carefully measure the thickness of the glass and divide that by two to get the correct setting tape. Check that with the width of the channel. C&G, our source of supply, sells four thicknesses: 1/32, 3/64, 1/16, 5/64.. Once in place, you trim the excess along the top of the channel. Tapes come in come width, 1 1/2", and 20 feet long. Order at 800/0470. Priced at $10 for the narrow width, $15 for the others.
