Prehanging
Select a single door, or choose a combination of doors / sidelites / transoms to prehang together. Any combination of items can be prehung at the factory for easy installation on the job site.
​
As standard construction, exterior prehung units from B.C. Door are hung in solid-wood jambs with commercial grade ball-bearing hinges.
​
Exterior frames are fully weather-stripped to provide a complete seal from the outside elements and are built with an extruded aluminum sill for durability and aesthetics; both being characteristics of a sophisticated entranceway.
​
To complete an exterior prehung package, doors are prepared for locksets based on your drilling specifications for a no-fuss installation.
​
Interior prehung units from B.C. Door are hung in your choice of jamb species & hinge finish and are drilled to accommodate your handle set.
Please contact your local B.C. Door representative for specific pre-hanging options and specifications as they may change from dealer-to-dealer based on local building standards.
Select A Door to be Pre-hung
Step 1
Browse our Digital Showroom and select the door / sidelite / transom you'd like prehung.

Determine The Opening Size
Step 2
Every home is unique, with specific requirements for each individual opening. The "Rough Opening" is the structural frame that surrounds a pre-hung door unit.
​​
With accurate measurements of the rough opening, you can confidently select the required door size to ensure a proper fit and an easy installation.
​
To reveal the structural framing of the rough opening, remove existing interior door casing. Once removed, measure horizontally from stud-to-stud, and vertically from subfloor-to-header. The subfloor is underneath your door unit and finished flooring.
​
It’s important to measure to the the nearest 1/16" based on the smallest dimension of the rough opening. This will ensure the new door fits in your home. For Width, measure at the top, middle, and bottom. For Height, measure as the left, middle, and right.
Determine Jamb Depth
Step 3
Measure from the exterior edge of the jamb to the interior edge of the jamb. When measuring, do not include interior or exterior trims - such as brickmold or casing.
Common jamb measurements are:
-
4-9/16"
-
5-1/4"
-
6-9/16"
-
7-1/4"
-
8-5/16"
B.C. Door can manufacture custom jamb sizes for unique applications upon request.
Hinge Color
Step 4
Most clients select a hinge color to coordinate with the color of the lockset they intend to install.
​
Actual hinge style and dimensions will vary based on application. Hinge images are representative of finish only.
Sill Color
Step 5
Mill Finish Aluminum (silver) is the most common sill finish selection, however, some clients select a bronze anodized finish color (almost black) to coordinate with the color of hinges & lockset specified.
​
Wood is also available for heritage or custom applications.
​
Actual sill style and dimensions will vary based on application. Sill images are representative of finish only.
Weather Strip Color
Step 6
Black is the most common color selection. White is available upon request for doors painted white.
Door Swing
Step 7
Door swing is critical to ensure proper functionality of the space immediately surrounding your door opening.
When replacing a prehung unit, most clients opt for the same swing direction as their current door.
​
'Swing Direction' and 'Handing' are specified based on the observer’s point of view as a door swings away from you. When a door "swings away from you," it means that you are facing the door and it opens in the opposite direction, moving away from your position.

NAFS Approved
Step 8
B.C. Door is capable of manufacturing prehung units that are NAFS approved for doors up 3'6" wide x 8'0" tall to meet all current BC Building Code standards. Sidelites and Transoms can be added to further increase the net-size of a prehung unit.
​
Speak to your B.C. Door representative for options on doors greater than 3'6" wide x 8'0" tall or very large Rough Openings.
Highly custom doors - particularly when oversized - are not within the scope of NAFS certification as it is not practical to lab-test these types of doors. In these situations, your homebuilder, architect, building-inspector, and B.C. Door representative should be consulted before your project begins to ensure compliance with all aspects of the Building Code.
Lockset Machining
Step 9
Modern tubular locksets require standardized machining. Typically:
​
-
Double Drilled with a 2-1/8" face bore for Latch & Deadbolt, and
-
5-1/2" spacing between the center of the holes
​​
Drilling Height is typically 36" from the bottom of a standard height door and up to 42" for oversize doors.​
​
B.C. Door is capable of custom machining for any tubular, mortise, or multipoint lockset requested.
Multipoint and Mortise Locks
Specialty Option
B.C. Door can prepare and install hardware with mortise pockets and/or multiple locking points for added security.
