Two sets of replacement Rubber plugs for all Super Feeders. NOTE ABOUT OUTDOOR USE:  Rubber parts, particularly the ones on the side of the feeder can shrink after very long exposure to sun rays and should be checked periodically to make sure that they are secure to prevent rain from seeping inside and corroding the electronics board, which could cause the feeder to continue dispensing food until the power is removed.  Animals could also pull them out. You should inspect them periodically and replace them as needed.
