Crown Moulding 4-1/4" - 5

This timeless classic crown moulding 4-1/4" - 5 measures 4.250" wide by .750" thickness. The ageless design is comprised of a 1/2" tall vertical line at the top, connected to a 1-1/2" concave cove tangent off of a 1" radius arc, these semicircles create the cyma recta in the center, joined to a 5/16" vertical line attached to a 9/16" cove with a 13/32" wide horizontal line at the bottom of the pattern. This stylish profile is the most widely used pattern in the industry, we offer hundreds of different sizes, simply enter the width size in the boxes provided to find the size that best suits your woodworking project.

The spring angles are fixed at forty-five degrees, these specific back bevels set the installed height at 3-1/16" tall with a projection of 2-15/16" wide. Read our commentary about axial constant positioning for crown bevels, the article will help you dial this profile in axially on the first try when milling this detail provided the machine is axially calibrated. Three high points in the detail were deliberately positioned on the same plane, our specialized design features will assure excellent hold down conditions while milling, providing the moulder pressure shoe is parallel to the machine bed plates.
