The Masonite 6-9/16″ Exterior Door Jamb Extension Kit is designed to increase the depth of your door jamb opening. It converts a door made for a 2×4 wall into a 2×6 wall. It includes a 36″ head, two (2) 82″ post legs and a 2″ sill extension in a roll anodized finish. Wooden parts are supplied primed and ready to paint.
Jamb extenders are an interior window feature that allows your frame to accommodate window openings of different depths. Extending the window jambs to the exact length required allows your window to sit flush with your interior wall.
Without mullion extensions, a skilled carpenter or drywall contractor must fill in the unused space with wood, drywall, or some other material before the window can be trimmed, so mullion extensions installed by the window fabricator can save on site labor costs .
Doorjamb versus doorframe
A doorjamb is a single section of a doorframe. Two side jambs form the vertical components of the door frame and the head jamb is the top horizontal component. Together the jambs (along with the jamb) form the door frame.
If the gap between the door and the frame is too small, you can widen it by adjusting the hinges. To bend the hinge, place the blunt end of a nail between the hinge leaves or against the knuckle. Slowly and gently pull the door shut and the nail set will force the gap to widen.
Door jambs, also known as “jambs,” are the insides of a door frame — specifically, the parts of the frame that hold the mounting hinges on one side and the striker plate for the door frame latch on the other side.< /p>
The top of the door is called the head, doorhead, or doorhead. A door jamb runs vertically along the side of the door. It supports the door panel and door frame. The piece at the bottom of a door is called a threshold.
