This quarter-round muntin moulding 1-1/4" - 1 measure 1.250" wide by .406" thickness enabling the use of a 1-1/2" wide blank of four-quarter lumber for milling on an industrial molder.

Ever notice why some moldings look better than other trim patterns in homes, offices, and older buildings. You may want to review our article on knife marks per inch. Read about how machine feed rates and rpm of cutter heads can directly determine the quality of the products you produce. Following or exceeding industry standards will allow your company to lead the way in molding artisanship.

Caution: the cutters will come within .020" of the machine bed plates when milling this detail. We recommend a wooden, phenolic, or plastic sacrificial bed plate for these types of milling operations.
