Interior Jam Options
SWS pre-primed jambs are imported finger jointed pine with a thin gesso primer that resists splitting and cracking. No field sanding necessary. All SWS clear jams are sold domestic ponderosa/southern yellow pine for excellent stain ability. Looking for a specific species of wood? No problem; our Millshed can fabricate any style of jamb out of a limitless amount of wood species to match your door.
PRIMED OR CLEAR FLAT BOARD JAMB W/APPLIED STOP
A 3/8″ X 1-1/4″ rounded corner stop moulding is applied to a flat 3/4″ board jamb using finish nails to create a double rabbeted profile.
PROS: Low cost, stop can be applied anywhere along jamb to accomodate different door thickness. Board jamb minus the stop in used for bifold and cased opening framing.
CONS: Applied stop will loosen over time, not recommended for high use, or heavy weight doors.
PRIMED OR CLEAR ADJUSTABLE (SPLIT) JAMB
A 1-1/16″ thick jamb that comes in two pieces. Inner frame attaches to door panel allowing installer to shim and hang door unit. Closer frame then installed to finish installation.
PROS: Casing comes factory applied to door unit on both sides. Fits a wide range of wall thicknesses without modification.
CONS: Not recommended for heavy weight doors. Only available for 1-3/8″ or less door thickness. Difficult to install without casing already applied to unit
PRIMED OR CLEAR DOUBLE RABBETED JAMB.
A 1-7/32″ thick jamb with a 1-7/16″ rabbet, and also a 1-13/16″ rabbet.
PROS: Jamb is one solid piece, achieving far better structural support than either a flat board or split jamb. Necessary shimming still required during installation. Single jamb can accomodate both 1-3/8″ and 1-3/4″ door thickness. Ideal choice if trim work is to be done on site.
CONS: Casing can only come factory applied on one side, other side shipped loose
PRIMED OR CLEAR SINGLE RABETTED JAMB.
A 1-7/32″ thick jamb rabbeted on one side only.
PROS: Jamb is one solid piece, achieving far better structural support than either a flat board or split jamb. Necessary shimming still required during installation. Ideal choice for heavy weight doors, and if trim work is to be done on site.
CONS: Casing can only come factory applied to one side, other side shipped loose.
