Door Jambs: Smooth, Stable, & Prehung Kits for Easy Install

Door jambs are the vertical parts of a door frame. They hold the door in place and help it open and close smoothly.
Good door jambs are made of strong materials like wood or metal. They keep the door aligned and stable over time.
Prehung jamb kits save time. They come with the door already attached. Just measure, install, and enjoy a perfect fit.
