Keep your budding artists' masterpieces protected during the drying process with the Copernicus Spring-Loaded Paint Drying Rack. Featuring 20 shelves, this mobile art rack provides protection and organization for up to 20 of your students' paintings and other artwork on paper, canvases, cardboard, and more. The durable, spacious metal shelves allow various works of art to dry flat, and each shelf is evenly spaced 1" apart to prevent smudging and ensure that artwork won't be compromised while drying. Designed for easy mobility and reliable stability in the art room, the portable drying rack features four 2" caster wheels that can quickly lock in place. The customizable rack spacers can be personalized with names to make it easy to identify and retrieve each student's painting, and the paper catch clips ensure that artwork won't slip out when the racks are lifted. Additionally, the paint rack features a lock down bar that firmly secures the racks in place as well as a removable paint drip tray to protect classroom floors from unwanted paint spills. The art rack frame measures 33-1/2" (85 cm.) H x 26-1/2" (67 cm.) W x 25" (63 cm.) D in its resting state and 47-1/2" (120.5 cm.) H x 26-1/2" (67 cm.) W x 25" (63 cm.) D when lifted up.
