   Mark,

   When someone referes to a knockdown or KD jamb, that means it's shipped to you in pieces. It's not put together like a prehung door unit. You get two jamb legs, a head jamb and a door. You put it together and you install it.

   *Ther are two kinds of steel frames: Knock-down and Welded. Welded frames are installed prior to drywall and are in one piece (welded together). Knock-down frames are installed after drywall and come in 3 pieces (they are especially good in remodeling and up-fits for this reason).Billy

   *Mark, if you have KD jambs there will be a miter joint at the head/leg cassing intersection. Welded jambs do not usually have a visible miter joint.A knock-down jamb has metal clips at the bottom of each side of the jamb legs. The clips are hidden by baseboard or may be notched into the plaster or drywall and finished over. The side legs are plumbed by adjusting the placement of the clips and an adjusting screw located near the top of each jamb leg. The jamb head is usually installed with matching slots and tabs that line everything up as it goes together.We use a ton of these things in commercial remodels. Look under the heading of doors in your local yellow pages. Find a supplier that sell steel doors and jambs, and go see them. Once you see how easy they go together, you will understand how easy it is to take one out, without any major damage.

   Could someone explain to me what a "knockdown" jamb is? And what the best way to remove one would be. Thank you.
