Kegco K199B-1 Kegerators are 1-Tap Beer Keg Coolers that are set up to tap most D System Domestic American Beer Kegs. It comes complete with a D System Direct Draw Kit, which features a metal lever-handle keg coupler that is compatible with most beers kegged in the United States, Mexico, and Canada. The Direct Draw System also includes a 5 lb. CO2 cylinder, a premium single gauge regulator, a chrome plated metal draft beer tower, and all of the hoses and fittings necessary to dispense a cold draft beer. The lightweight 5 lb. Aluminum CO2 Tank is shipped empty and does not come filled. When full, the 5 lb. tank is good for approximately five-six full size kegs. The Single Gauge Regulator measures Pounds Per Square Inch (PSI), features a Safety Blow Off at 55-65 PSI, and comes with a flow control inlet nipple filter as well as a permanent Quad-Ring Inlet Seal. The K199B-1 Keg Beer Refrigerator also comes with two removable wire shelves that allow it to be converted into an All-Refrigerator or Beverage Center, making it a very versatile keg beer cooler. 2-1/2" Casters are provided for mobility, allowing you to easily move your beer fridge from the kitchen to the patio. The elegantly designed all-black cabinet has a field-reversible door, textured serving top, and metal safety rail that prevent your beer mugs from sliding off. Inside, it has a stainless steel floor plate that distributes the weight of the keg evenly and allows it to slide in and out without harming the plastic interior liner. These Kegerators can hold a Full Size, Quarter Slim, or Straight Pony Keg, or up to two Sixth Slims, Rubber Homebrew Kegs, or Strap Handle Kegs. Please Note: They will not fit Bevel or Rubber Kegs, which are commonly used by Coors and Miller Brewing Companies. Those kegs are wider in the middle than at the top or bottom.
