Abstract: An angled pool table rail-mirror for teaching players how to execute bank shots comprising a reflective surface disposed on a base which fits under the rail cushion of any standard pool table. The mirror is fixedly angled to a position which enables the shooter to line up virtually any bank shot while standing in a natural shooting position. The base of the rail-mirror possesses a knurled surface which secures the device under the rail cushion and prevents it from being inadvertently knocked out of horizontal alignment with the rail.
