Hinge Jamb moves after installation

Need to install a new frame in an existing wood stud opening that is already drywalled. I can get the frame square and plumb but when I hang the door on the hinge jamb it wants to move. The area is already carpeted and the owner does not want any thresholds so a reverse base anchor is not the answer for securing the jamb.

You would have had to use a knockdown drywall (KD DW) frame as you are going into a stud wall with the drywall already up. These come in 3 separate pieces. There are "compression anchors" in the top of each jamb and pre drilled holes on each side of each jamb at the bottom.

If you don't have these holes at the bottom you may have to drill them as some frames don't have them but come with clips instead. If your frame is moving you either don't have these clips, didn't install the screws in these holes, and/or you didn't tighten the compression anchors at the top.

To install it you slide the head in place over the wall, install the hinge jamb by aligning the tabs in the top of the jamb with the slots in the head and pushing it over the wall, and install the strike jamb the same as the hinge jamb. Pull the head down tightly with the jambs and level by shimming at the base of the jambs if needed. Tighten the compression anchors, make sure the frame is square and level, and install sheet metal screws in the bottom holes.

Another option, which wouldn't look the best but would certainly get the job done, is to Punch & Dimple the jambs. This is most commonly done with existing concrete walls or putting in frames after the block has been laid. This picture shows a Redhead, but you would use 3/8" x 5" or 3/8" x 4" wood screw.
