Porter-Cable 4212 (29550) instruction manual BOX Joints, Cutting the First Workpiece

BOX JOINTS

Box joints have straight protrusions that interlock and must be held together by glue. The large amount of gluing surface provides the strength necessary for large projects.

NOTE: If you are using the 4210 dovetail jig, you will need the 4213 accessory kit to make this joint. You will need the 4215 accessory kit for the miniature box joints.

Box joint fingers are spaced in 1" increments (1/2" for miniature).
