Plinth blocks are placed at the bottom of doors next to the baseboard. The casing is applied between the plinth and the upper corner rosette. Blocks are normally 1/4" to 1/2" wider than the casing leaving a nice reveal on each side giving the treatment a grand look.
You may choose the plain plinth and pair it with a corner rosette block.
ALL PLINTH BLOCKS ARE SOLD UNFINISHED. Most pictures are shown with a clear coat finish.
