Ready-Fit. Paint-Ready. Perfect Swing.
A clean, architectural frame that arrives pre-machined for hinges so your slab hangs square and swings like silk. Milled from solid Paulownia—a notably lightweight, easy-to-finish hardwood—and factory-primed for a porcelain-smooth, paint-ready surface. Order the jamb sized for 78″ or 80″ door heights (80″ is today’s most common interior standard), then set, fasten, touch up, and admire the quiet precision.
Features
- Purpose-built frame components: Door jambs are the vertical and top members of the frame that carry the hinges and align the latch side for smooth operation.
- Pre-machined hinge mortises reduce layout time and ensure repeatable placement (standard on quality jamb kits).
- Material: Paulownia hardwood — very lightweight, straight-grained, easy to machine; accepts glue/primer/paint well.
- Finish: The factory-primed, paint-ready surface arrives for light sanding and topcoat.
- Heights supported: 78″ (common in older or specific applications) and 80″ (the prevalent U.S. interior standard).
- Install flow (summary): Plumb/level legs, fasten, hang slab on pre-cut mortises, set reveals, add stop/casing, then finish paint.
