We developed this spray bottle rack after one of our nice customers said he wanted his favorite Griot's Garage car care products conveniently available. Now you can actually find that bottle that used to hide behind all that mess on the shelf. Great inside cabinets as well as on walls. The 21 5/8" long powder coated metal rack holds six 3" diameter cans or bottles (mounting holes are 16" apart). Perfect for paints, lubricants and car care products. Mounting hardware included.
