Jim - I guess it's different - couldn't get at the glass channels right now, but tho' they're prolly the same width [same glass thickness], they're only about 1/2" deep, plus the roller channel which screws on below - the
roller channel is about 7/8" overall, and the roller thickness would be about 1/4", diameter about 3/4" [gap for the arm that holds rollers is about 5/8] - about 16" long, so would take 2 for 1
