Installation Guide
Tips: 
•
Both edges of the molding should be flush with the sides of your 
miter box or saw. This is important for keeping the cuts consistent. 
•
Not all walls will be structured at a perfect 90° angle. You can adjust 
your miter angle on a miter saw if necessary. 
•
Cuts are made with the profile upside down. As you cut, the ceiling 
side (C) of the profile will be close to you and the wall side (W) will 
be away from you.

Cutting your crown molding “In Position” refers to cutting it at the angle in which it will be installed. This is 
recommended for first-timers and for those who will be using a miter box and hand saw.
