When you install a piece of equipment that has a 10 year warranty, you need to try to use the type of hardware that will also last 10 years or more. These stainless steel wedge anchors may seem a little bit high to the average customer…but they will be doing their job through all the mud, the blood, and the beer – in other words, they will take the corrosiveness and abuse of manure, urine, water, heat, cold, and time. These parts may be hard to find at your local hardware store so we make them available to you when you are ordering your waterer. The (4) fender washers you see in this photo are the ones you get with the fountain and are not included in this purchase. Make sure you use them in the installation of the waterer.
