Proper frame installation cannot be overemphasized. In the majority
of wall constructions, (“slip-on” drywall type frames being the
major exception) “quick” or “easy” field fixes are limited. Improperly
set frames that are drastically out of square will cause severe door
and hardware problems. These types of situations would require
extensive field repair and may result in having to remove frames
from walls to gain access to frame anchoring.
If the “out of square” condition is slight, some adjustment can be
made by shimming and/or adjusting anchors, particularly if the
frame being worked on is a slip-on drywall type.
The most versatile frame to work with in correcting these types
of conditions is the “slip-on” drywall frame. The manufacturers’
instructions should be referenced, but generally most “slip-on”
drywall frames have a sill anchor at the bottom of the jamb and a
compression anchor between the top hinge and the header. Also,
most jambs have corner clips that have a hole to accept a screw. The
corner clip and hole align with a hole in the header. The adjustment
of slip-on drywall frames can be made using these anchors
