Shorter studs that support the ends of a header, which in turn supports the load of the studs above the opening. Also called trimmers. Back to alphabetical list ...
: framing members, generally 2'x4's, which form the inside of the window or door rough opening, running from the sole plate to the header
Jamb: the piece of a window or door that stops the sash from continuing to close ...
Jack Stud - A partial stud nailed next to full studs to support the header at door (and some window) openings.
Jamb - An exposed upright member on each side of a window frame, door frame or door lining.
(poteau nain, m.) A block or short stud nailed to rough door or window studding to add strength and provide a solid bearing for the lintel and nailing member for the finished door jamb or window frame.
Also called a jack stud. A vertical member that supports the header in an opening of a bearing or supporting wall.
Almost every board is curved slightly. The crown is the top of the curve of a board.
Vertical framing members, generally 2x4's, which form the inside of the window or door rough opening. They support the header and run down to the sole plate.
Vertical wood member at each side of the rough opening for a window or door and supports the header.
: Studs that are used to support the heavier framing at both sides of a door, window, or other opening.
Jamb: The side and head lining of a doorway, window, or other opening.
Cut two jack studs to the height of the rough opening, nail these to full-length, or king, studs so their bottom edges are flush, and secure these doubled studs to the floor plate at the rough-opening marks.
An extra vertical supporting member in a frame wall or partition over a door, window or archway. Jalousies Adjustable glass louvers in doors or windows that regulate light and air or exclude rain.
5. Select the two Jack Studs, measure, mark, cut the Jack Studs to the dimensions of the lower portion of the vertical rough opening; subtract 1 1/2" to allow for the thickness of the Base Plate; nail the lower Jack Studs in place.
The first studs on either side, the s, go only as high as the rough opening of the doorway. On top of those go a double header. Since it is none load bearing a 2x6 header is sufficient.
The vertical pillars supporting each end (normally composed of 2x4s or 2x6s) are called king studs and trimmers (or jack studs). In most wood frame dwellings, headers are made of dimensional lumber installed on edge.
Running from side to side, between the studs outlining the rough opening and supported by partial studs called s or trimmers, the header supports the weight of the door or window.
Step 4: Install a New Header and Jack Studs
Measure, cut and install a new header and nail it in place over the trimmer studs. Toenail the cripples to the header. Once the cripples are secured to the header, the temporary brace can be removed.
Door openings commonly have two king studs and two s. A king stud is one that runs continuously from the top plate to the bottom plate.
This method is essentially the same as framing a door opening and filling in the lower area with jack studs and a sill that runs between two trimmer studs.
Step 9. Nail the king studs, s, a header and a cripple stud in place to complete the rough door framing.
Where there is a doorway or a window, a special form of bracing needs to be done. The jack studs act like regular wall studs. They help brace the trimmers and the headers.
Openings for windows or doors must be framed in studs. This framing consists of horizontal members (headers) and vertical members (trimmers or s).
