What is a door jamb?
A door jamb is the frame component around a door opening. It is different from casing, which trims the outside of the opening, and different from door stop, which helps stop or position the door in the frame.
For search and RFQ clarity, DL Moulding treats door jamb as its own product family. A white primed jamb should not be renamed casing, baseboard, or generic moulding when the visible product body and intended application are door jamb.

Profile references
Flat, rabbet, and split door jamb references
with dado is a machining detail
When a jamb requires a dado or other machining detail, describe it with the jamb profile, dimensions, material, finish, quantity, packing, and intended installation.
Use dimensions and visible profile details
For split door jamb review, buyer-facing communication should focus on dimensions and the visible section. Internal tracking codes should not appear on public product cards.

Overview
Door jambs are used as structural and finish components around door openings. Buyers can share jamb width, thickness, length, stop details, surface finish, and packing requirements for review.
Rabbeted jamb and flat jamb options
Rabbeted door jamb profiles include a rebate detail for the door assembly. Flat door jamb profiles use a simpler flat section and may be matched with separate stop details or market-specific installation requirements.
Split jamb and machining notes
Split jamb requirements should be reviewed with the visible section, size, material, finish, opening requirement, and packing plan. If the request includes dado, rabbet, or stop details, treat them as machining details tied to the jamb, not as separate product categories.

FAQ
Door jamb buyer questions.
What is a door jamb?
A door jamb is the frame component around a door opening. It should be specified by jamb width, thickness, profile detail, material, finish, and packing requirement.
Is a rabbeted door jamb the same as casing?
No. A rabbeted jamb is part of the door frame opening. Casing is trim around the opening and should be quoted as a separate product when required.
Can DL Moulding review custom door jamb dimensions?
Yes. Send the drawing, sample photo, jamb size, machining detail, material, finish, quantity, packing notes, and destination for review.
How do I specify a split door jamb?
Send the visible section drawing or photo, dimensions, material, finish, required opening detail, quantity, packing notes, and destination. Dimensions are more useful than internal tracking codes for buyer-facing review.
Is a door jamb with dado a separate product?
No. Dado is a machining detail. It should be described together with the jamb type, profile drawing, size, material, finish, quantity, packing, and installation requirement.
Need a door jamb quote?
Send jamb dimensions, stop requirements, material, finish, quantity, and destination details. We will review the requirement and reply with the next step.
