Assembly for coping and mounting trim molding

A method for installing a finish trim molding on a wall, the method comprising:

• mounting a trim holding device on the wall, the trim holding device comprising a mounting bracket configured to mount in facing contact with the wall, the mounting bracket further comprising a pair of mounting flanges disposed on the mounting bracket, the pair of mounting flanges being substantially horizontal and extending perpendicularly outward away from the mounting bracket and the wall;
• and
• mounting the finish trim molding onto the trim holding device, the finish trim molding defining a pair of channels, the pair of channels being substantially horizontal and defined perpendicular to a vertical rear surface of the finish trim molding, the pair of channels configured to receive the pair of mounting flanges, and
• wherein the trim holding device is mounted adjacent to an upper corner of the wall and a ceiling, the trim holding device further comprising a ceiling stop disposed on a top of the mounting bracket extending upwards from the top of the mounting bracket substantially parallel to the wall and substantially perpendicular to the pair of mounting flanges, the ceiling stop resting adjacent the ceiling and configured to provide spacing to fit the trim molding between the wall and the ceiling.
