The 35 Ounce Bottle Rack holds four of our 35 ounce spray bottles and is 21 1/2" wide. It's made from 18-gauge steel, finished with a durable red powder coating, and mounting holes are 16" apart. Mounting hardware is included with your racks. Now you can actually find that bottle that used to hide behind all that mess on the shelf. (Car care products sold separately.)
