Where can I get a good divider that will not fall. Also on ebay there are some penn brand suction cups that hold a divider, my question is will they hold the plexi glass that they sell at home depo?
Egg crate from Home Depot and put suction cups on each sides to hold them up. Egg crates you can cut down to size with pliers/wire cutters. But if you don't like the look get a sheet of acrylic/plexiglass cut it to your size and you can get suction cups to hold your sheet still.
