Solid Fir Jamb

Solid Fir jambs, or frames, go great with our Fir Simpson inventory. The frame material is a vertical grain fir and stains easily to help the customer get a consistent finish with the door and frame components.

Reeb Finish

This jamb species cannot be finished by Reeb Finish.


Solid Fir jambs can be used with single doors, double doors, doors with one sidelite and doors with two sidelites.


This jamb is stocked in two sizes, 4-9/16” and 6-9/16” Anything larger than 6-9/16” will be a built up jamb that is cut back from other frame stock and glued back onto the original jamb set. Transom sills are available in 4-9/16” and 6-9/16”.


All standard heights are available for this type of frame.

Exterior Casing

Brickmould and flat casing are available as an exterior trim in a matching fir material. The Brickmould will be 2” in width. The flat casing is 1×6 (nominal measurement of 3/4” x 5-1/2”).
