A pre-hung door consists of a door hung on hinges and assembled in a wood frame with a door stop (the frame is also called the door “jamb”). A pre-hung door is ready to install in the door opening, with no on-site assembly required. This reduces construction time and scheduling, lowering project cost. If the pre-hung door is also pre-finished, this further reduces steps and cost in the construction process.
In addition to manufacturing the highest quality door slabs, we also offer optional pre-hanging of the doors. Factory pre-hanging ensures that hinge pockets are mortised square and precise, and that hinges are always flush on the door and frame. Hinges are included in the price of pre-hanging and are available in a selection of color choices. Boring and latch/dead bolt mortising are also provided at no additional cost with factory pre-hanging. A choice of single or double bore options are available in different “backset” positions (the placement of the handle or lockset from the door edge). Factory pre-hanging also ensures that the “reveal” (the small gap between the door and the jamb, when the door is closed) is always correct.

If optional pre-hanging is selected, we offer solid Knotty Alder wood jambs—much higher quality than “finger-joint” jambs made of scrap lumber joined together in multiple places.
Our door jambs are flat jambs with an adjustable stop. Our jambs have eased (rounded) edges on the facing side of the jamb. If we also pre-finish the door, the jambs and stop are finished separately (matching the door Stain or Stain/Glaze color), allowing for on-site adjustment of the stop without finish touch-up.
We also offer kerfed flat jambs, in solid Knotty Alder. Kerfed flat jambs are slotted on the edge for wrapping the drywall corner bead (rounded or square drywall corners) into the jamb. Kerfed flat jambs provide for a clean opening, with drywall connecting directly to the door fame, and no case mouldings.
Door hinges are square corner 3.5” hinges. Nine different hinge colors are available, at no additional cost.
Flat (non-kerfed) door jambs are available in the following widths, to match the following wall stud and sheetrock thicknesses:
Solid Knotty Alder, Flat Jamb w/Adjustable Stop
|Stud, Sheetrock Thickness||Flat Jamb Width|
|2×4 Stud, 1/2” Sheetrock||4-5/8” Wide|
|2×4 Stud, 5/8” Sheetrock||4-7/8” Wide|
|2×6 Stud, 1/2” Sheetrock||6-5/8” Wide|
|2×6 Stud, 5/8” Sheetrock||6-7/8” Wide|
Kerfed flat jambs are available in the following widths, to match the following wall stud and sheetrock thicknesses (Note: Kerfed flat jambs are more narrow than regular flat jambs, to allow for wrapping the drywall corner bead into the jamb):
Solid Knotty Alder, Bull-Nosed Kerfed Flat Jamb w/Adjustable Stop
|Stud, Sheetrock Thickness||Flat Jamb Width|
|2×4 Stud, 1/2” Sheetrock||3-1/2” Wide|
|2×4 Stud, 5/8” Sheetrock||3-1/2” Wide|
|2×6 Stud, 1/2” Sheetrock||5-1/2” Wide|
|2×6 Stud, 5/8” Sheetrock||5-1/2” Wide|
Handing and Swing refers to the side of the door that is hinged, and the way the door swings inside or outside of the room. Consider the way you would like your door to open when making this choice.
A simple way to understand handing is to stand in the doorway with your back against the jamb of the door where you want the hinges to be placed. From this position, if you want the door to open to your left, it is a left-hand door. From this position, if you want the door to open to your right, it is a right-hand door.
Next, determine if you want the door to swing inside or outside the room. Inside is an “inswing” door, and outside is an “outswing” door. Review the illustrations below to identify the way you would like your door to be handed and swing (Note: These illustrations apply to single doors).
For double doors, one door is designated as “active” (operating knob or handle to open the door), and the other door is designated as “inactive” (still opens and closes, but no working knob or handle). The inactive door includes an attached “T-astragal” with flush bolt (top flush bolt only) to secure the door in the closed position. Review the illustrations below to select which side of your double door you would like active, and its handing and swing (inside or outside of the room).
In addition to these handing and swing options, we also offer double doors with a “Ball Catch” or a “Bypass” configuration. These double door options are most frequently used on closet door applications. For example, Ball Catches are typically used with “dummy” (non-active) handle sets, on outswing closet doors. Ball Catch hardware is included at no additional charge on double Ball Catch doors, and track hardware is provided at no additional charge on double Bypass doors. We do not bore for the dummy handle sets on these options. Review the illustrations below to select one of these double door applications.
When you order a pre-hung door, we can bore your new door for a handle or lockset, at no extra charge. We offer both single bore and double bore options. Our bores include mortising the edge of the door for the latch (latch and dead bolt for double bore) and mortising the “strike” on the jamb leg (where the latch inserts, or latch and deadbolt for double bore).
The first bore is always 36” from the bottom of the door, and the bore hole diameter is always 2-1/8”. For double bore options, the distance between the two bore holes is always 5-1/2” center to center (from the center of the diameter of one bore to the center of the diameter of the other bore). If these bore positions and dimensions do not match your desired hardware, please contact us to order custom specifications. Alternatively, you may select the “No Bore” option, and have your new door bored for hardware by your installer.
Available “backsets” (the distance from the edge of the door to the center of the bore diameter) are:

Crating and Shipping Pre-Hung Doors
All orders are shipped direct to the home or jobsite in sturdy crating. Single door units are shipped pre-hung (as applicable), ready to install. Pre-hung double doors are shipped “Knocked Down” (or KD) and must be re-assembled prior to installation. Freight and crate charges are calculated based upon volume (door count) and are assessed at the time of check out.
