Interior door production begins with precision-cut casing, shaped to exact work order specifications using a CNC trim saw. We assemble two vertical casing sides and one horizontal casing head into a “hoop” using a backnailer, then stage it for the production line. We machine jamb materials at our automated strike router and head-cutting station to ensure alignment with project specifications. Door slabs are selected and staged at the start of our horizontal door line, where we machine, hinge, label, and advance them through assembly. Strike and head jambs are joined at a clamping station that squares the frame and verifies dimensional tolerances. Once framed, we apply casing hoops, add corner protectors, and stage finished units for loading or direct placement in the trailer.
