Chair Rail 4" - 77

This 4" - 77 belly-band chair rail measures 4.000" wide by 1.000" thickness, requiring the use of five-quarter lumber for machining on an industrial moulder. The unique graceful profile is composed of a 1-17/32" convex arc in the center, flanked by two tangent 7/8" concave semicircles and a 9/16" arc with a 1/4" round-over on each side edge of the design. Caution; the cutters will come within .020" of the machine bed plates when milling this detail. We recommend using a wooden, phenolic, or plastic sacrificial bed plate for these milling operations.
