A week later I had delivery

The rough opening called for 16" X 16.37" , not trusting my measuring skill with such an important cut, I traced the back of the unit on cardboard & made a templet, taped it to the bulkhead & traced it.
Looked at for a while & made the cut
Unit went in perfect. The instructions called for stainless screws, but I used stainless bolts & lock nuts, backing it up with 1" X 2" strips of aluminum on the back for a little extra strength, & sealed front & back with silicone. This unit came with 5 plano trays, the bottom one larger that the top 4.
