This ball valve fits on the end of a 3/4″ threaded drain pipe to help drain food drippings out of your Holland. You can also close it off to use the steaming feature of The Holland Grill. It also has a convenient hook to hang your drip bucket on and the Holland Logo stamped on it. (Note: This product does NOT fit the original drain pipe of The Maverick grill or older Hollands that use a 1/2″ drain pipe.)
