Just give them a call and they can make sure that you order exactly what you need. This is something that anyone with basic DIY skills can do to transform their fireplace. Most of the work was in taking out the old gas fixture and then cleaning, prepping and painting the hearth. They now have spray paint that can stand temps up to 2000 degrees. I replaced the dated brass-framed doors with a glass screen that really compliments the bed of multi-colored glass. We went with clear, golden and copper mirrored glass 1/2-inch pieces. Rinsing the dusty glass was a pain but did leave it very shiny. This was a fun project that definitely was worth the money and effort. I am giving them five stars. However, they would not make the unit with a left-hand-side regulator/standing pilot. So, I had to run a longer gas line around the right and bury it in the glass. Not a big deal.
