A great door deserves a solid frame. Our paint-grade door jambs give you a clean, square, professional finish — and make installation far easier.

Two materials

Raw MDF, or factory-primed finger-joint pine — both paint-grade and built to last.

Sized for your walls

4-5/8″ for 2×4 walls and 6-5/8″ for 2×6 — the right depth for a flush fit.

Built to last

Strong, straight jambs that carry hinges and hardware securely and resist warping.

Finish your way

Primed pine arrives paint-ready; raw MDF sands and paints up smooth and clean.
