Crown 3-1/4" - 30

This concave 3-1/4" - 30 crown mould measures 3.257" wide by one-inch thickness, allowing the detail to be milled sprung (horizontally flat) out of four-quarter lumber. The embellishing profile is composed of a 1/2" tall vertical line at the top, joined to a one-inch radius cavetto tangent off of a 3/4" tall vertical line segment in the middle, attached to a 1/2" tall by 3/8" wide notch with a 3/8" broad flat line at the bottom of the pattern. The spring angles are fixed at thirty and sixty degrees, these specific back bevels set the installed height at 2-3/4" tall with a projection of 1-3/4" wide.
