The frame a door hangs in. Every CK prehung unit arrives with the jamb already assembled to the slab and the hinges fitted — sized to the opening, so the unit goes into the rough opening without rework.
Three parts do the work: the frame that carries the hinges, the stop the door closes against, and the casing that dresses the opening. Profiles are confirmed per order.
Full trim profile list and lengths are on the Wood Trim page — tell us what your project needs and we'll confirm what we can supply.
The same choices apply across our door categories, so repeat orders land the same way every time.

A jamb is not an accessory — it is the frame the door swings in. When the jamb, the hinges and the handing are all decided at the same time, the unit drops into the opening on site and stays square.
