Our replacement expandable rubber drain plug with bolt can be used with a variety of waterers.  The wingnut is used to tighten and creates additional pressure to provide a better seal.  It can be removed to drain the trough for quick and easy cleaning. 

The wingnut is made of Poly material to prevent corrosion.  The bolt is constructed with stainless steel and will not rust, extending the life of the plug.
