the tank divider you are probaly talking about is not made anymore. there are different types that are similar, but cost $50-100 a piece. the simplest way to divide a tank is to use plexiglass. i created a 1/3 land to 2/3 water tank in a 20 gal long for my firebellies. all you need is a piece of 1/4-3/8" thick plexiglass, a tube of aquarium silicone and a warm day when you can do it outside since the silicone will smell for a day or two while it cures. cut the plexiglass at the proper length to fit across the tank (you can either score the plexiglass a couple otf times with a razor knife or carefully cut it with a table or circular, but use eye protection if using the saws) and the proper height to allow for about 1/2" to an inch of glass sticking abov ethe waters surface, i.e., if the water is six inches deep, cut the plexi 7 inches high. determine the angle at which you want the plexiglass to be, ususally about 80 degrees or about the angle of the slash mark ( / ). determine where in the tank you want the plexiglass and run a bead of silicone along the outline of the tank where the plexiglass will meet the glass of the tank, set the plexiglass in the silicone and let it set for 2 minutes, you my need to hold or prop up the plexiglass until it gets tacky, then silicone the around the plexiglass on both sides and smooth out. then let it dry for 24-48 hrs and your good to go.
hope this helps
