    Abstract: The invention is a paint roller corner cover consisting of a cap made out of any suitable material having a circumference equivalent to that of a paint roller cover and having a narrow circular annular base with a holding mechanism consisting of lugs which are evenly spaced around the outside of the end cover cap to serve as a holding mechanism. The outside surface of the end cap is matted with a napped material Which is to be similar or identical to the nap material on the paint roller. This device provides a paint roller corner cover which effectively paints a 90 degree corner and which results in a smooth final surface area.
