Backout/Relief Cut 4" - 3 
   Backout/Relief Cut 4" - 3 
  This backout 4" - 3 measures 4.000" wide. This fluted profile is intended to be utilized on the backside of many of our smaller sized 
crown and 
coves. These concave plows will help keep the crown or cove profile from cupping and becoming out of square after the milling process.
 
The profile comprises two 13/64" radius flutes, separated by a 1-5/8" wide fillet in the center, a 13/16" wide fillet on the inside edge, and a 1-1/16" wide fillet on the outside edge of the pattern.
 
To help you better understand why backout or relief cuts are used in moulding design, please refer to our helpful article titled Moulding Backout Relief Cuts. After reading this commentary, we trust you will find the appropriate relief cut design for your customized moulding pattern.
