1/2″ Valve Bracket Package with 2 screws and washers for the StallFount II’s. This bracket bolts inside the StallFount II’s and gives you a 1/2″ fpt thread to screw your 1/2″ float valve into. It has a 3/8″ barb lead-in so your 3/8″ rubber hose can connect up using the small worm gear clamp that comes with your fountain. You can also order the 11515 bracket package. It has a couple extra screws in it that you won’t use – those other screws are for other models of fountains that also use this bracket.
