Welcome

The Crown Master Mitre Box (CMMB) is easily adjusted to accept any size crown molding up to 4½” wide. It also easily adjusts to any angle of tilt for any particular molding.

The CMMB easily creates the ability to cut mitred joints in crown and other tilt moldings for angles of 1 degree to 45 degrees, and the auxiliary fence attachments easily accommodate the more difficult cuts of extreme mitres of 45 degrees and greater.
