Our chrome wire shelving racks are our most popular selling product because of the wide range of sizes, strength and shelf spacing flexibility. Each shelf is fully adjustable every 1" on our chrome posts with double grooves every 5" to make measuring simple. Each shelf is held on the posts with a tapered plastic split sleeve that clips on the post and holds the shelf securely in place. Once shelves are in place they can easily be moved to adjust position as many times as needed.
