The Crown King jig lets you cut perfectly mitered
interior (INT) and exterior (EXT) corner joints—
right out of the box—on 38, 45, or 52 degree
(spring angle) crown moldings. Moldings are cut
the way they look on the wall.
Positioning of insert for 38◦ cuts.
Crown moldings may be installed
either-side up, however, the
spring angles will be different.
For a 45◦ spring angle
Insert is not needed.
Markings on the insert
quickly help you to posi-
tion the insert for the
correct spring angle of
38 or 52 degrees.
38◦ spring angle 52◦ spring angle
To check molding angle before cutting, place molding
in jig; the wall face angle should be vertical and the
top (ceiling) angle horizontall. ). If the ceiling angle is
not horizontal, rotate or remove/insert yellow plastic
adapter until angle is correct.

Cutting sequences are simplified by guide marks
embossed on the jig top. All interior (INT) and
exterior (EXT) corner miters for left-side mold-
ings are made on the left side of the blade; cuts
to the right-side moldings are made on the right
side of the saw blade.
Positioning of insert for 52◦ cuts.

1. MEASURING AND LAYOUT
Measure interior (INT) or exterior (EXT) corners.
Divide the angle in half and set the saw blade to
this number.
Position the jig and the molding on the miter saw
table with the jig against the saw fence as far
back from the saw blade as needed. Moldings
are hand-held for cutting.
