Server Free Flow Kit Only -- 1 each.The Free Flow Kit can be an effective tool for fine powders that tend to bridge. A quick twist of the handle breaks up any product that has bridged allowing the product to flow freely again. Keep in mind, toppings that melt in an ambient serving environment will do so in the dispenser as well. That means crushed candy bars are not a good fit. The double dispenser with stand, pictured lower left, shows an installed Free Flow Kit. Free Flow Kit (86625) is designed specifically for Server Products Dry Product Dispensers with a 2-Liter capacity. Please take note of the slight change in the dispenser lid shape; when combining dispensers with and without a Free Flow Kit.
