What We Like About The Wesco Greenline Panel CartThe most convenient aspect of this cart is definitely the side loading rollers. Usually, one must be very careful not to scrape the side of heavy panels on the edges of carts, but with the rollers one person can do the job without worry. They are as useful for taking panels out as well. The center compartment has removable rods which can be removed or left in place to support an included plastic bin. The standard size can hold up to 1,543 pounds while the larger, heavy-duty model supports 4,000 pounds. Removable plastic basket. Detachable center bar. Perfect for sheet products. Rollers for easy loading. 4 inch phenolic casters. Available in standard size or a larger, heavy-duty size. Volume Discounts Available - Call 866-736-2084.
