Thanks for the answer. I was confused because the pictures show the top with some overhang from the support strips, but the support strips were 1.25" from the cabinet front. Thus I read it as the top should be 3/4" from the front. 1/2" makes more sense to me if the marquee retainer + 2 sheets of lexan are still supposed to be 3/4" recessed.
Thanks again,
Stephen Goldberg
