This 14" x 60" Metroseal 3™ Wire Shelf features a green epoxy coating that has built-in Microban® antimicrobial protection which helps keeps shelves "cleaner between cleanings" by inhibiting the growth of bacteria, mold, and mildew. Metroseal 3™ is recommended for use in high humidity or wet environments and is guaranteed to resist rust and corrosion for 12 years. Metro's Super Adjustable design features a lever release adjustment, making them easy to precisely position in 1" increments along the grooved and numbered posts. Super Adjustable levers make re-positioning shelves easy, simply lift the levers and slide the shelf up or down the post - no need to remove the shelving to adjust split sleeves. The open wire design reduces dust accumulation and allows proper air circulation.
