Installation Guide

Casing can also be installed using corner blocks and plinths. A corner block is installed at the top of the
opening. It takes the place of the miter joint where the vertical horizontal pieces of moulding intersect.
A plinth block is installed at the bottom of the vertical piece next to the floor. The bottom of the casing
will end on top of the plinth and the base board will butt into the side. Using blocks eliminates the need
for mitered corners simplifying the installation. Only square cuts are needed as the moulding will be
installed between each block.
