STEP 1

Preparation of the wall

The wall case should be installed during construction
and lintels should be used to support the block above
the wall case. The case will not support the concrete
block or brick. The case is modular in height and
width:
Height — Fits 2 courses concrete block
— Fits 6 courses standard brick
— Fits 5 courses jumbo brick
Width — Fits approximately 2 stud spaces.
For existing construction, wall openings must be
made. Wall openings of the proper dimensions are
essential to avoid the necessity of fillers or additional
framing.

STEP 2
Preparation of the case
If field-supplied case angles are to be used and must
be installed, proceed as follows:
1. Position the case angles around top and sides
of the case at the desired location (front to rear)
with angles facing toward rear (outside). Position
the case angles vertically on each side of the case
to provide a level installation.
2. Mark the case through the holes in the case angles.
3. Drill 5/32" diameter holes at marked locations
on the case and assemble the angles using only
10×1/2" screws. Install the screws from the
outside of the case.
NOTE:
Do not drill any holes in bottom of the case.
