This 168 Bottle 7-Shelf Wine Rack is constructed from industrial-strength UltraZinc plated steel and ideal for any wine lover! The zinc plating process provides added corrosion resistance and is better for the environment (compared to chrome plating) as fewer harmful chemicals are used in the plating process. Each shelf has specially designed contours that elegantly secure each bottle. This durable wine rack is NSF certified for commercial use, measures 14-inches by 36-inches by 64-inches high, and is backed by a 10 year limited warranty. You can build one tall unit or two smaller side-by-side units. It’s ideal for use in one’s kitchen, pantry, restaurant or wine cellar, and the perfect gift for any wine enthusiast.
