These frames are intended to be installed after the wall construction is complete. The anchoring methods that
this type of frame uses allows the removal of the frame if so desired. The manufacturers’ installation instructions
should be followed anytime the frame is removed and reinstalled. Three conditions could exist for drywall slip-on
frames which are “loose on the wall.”
1) The first condition is a uniform gap along the entire length (height) of the frame jambs. The frame should be
removed from the opening and the wall thickness checked at numerous places around the opening. These
measurements should be compared to the job specifications. If the wall thickness is undersize, two options
a) If the gap is relatively small, the use of caulking or trim can be considered to cover the gap when the
frame is installed.
b) If the gap is larger, the use of “spacers” can offset the lacking wall thickness. The use of spacers requires
that the frame be removed from the opening, the spacer(s) attached, and the frame reinstalled. The
spacers can be used on either one or both of the frame returns which would result in spacers on either
one side or both sides of the wall. Spacers are available from the frame manufacturer.
