No. 4 Duct
No. 2 Duct
IMPORTANT: Please read all instructions
before beginning.
Step 2. Core drill a 6 1/2" or 7" [165mm or 178mm]
diameter hole in concrete.
CAUTION: Do not cut into the duct.
Step 3. Loosen and remove concrete slug. Step 4. For two- and three-gang: Core drill another 6 1/2" or 7"
[165mm or 178mm] diameter hole over duct keeping
holes at 4 1/8" [105mm] on center. Loosen and remove
slug after coring is complete.
Step 5. Using a 2 1/2" [64mm] diameter hole saw, drill
opening in center of duct. For two- or three-gang,
use template for proper center locations.
NOTE: Holes in No. 4 duct will not be located in
center of duct. Center of holes must be
4 1/8" [105mm] apart.

Step 3. Loosen and remove concrete slugs.
Step 2. Mark concrete with cutting lines based on single-,
double-, or triple-gang afterset to be installed. Opening
should be approximately 1/2" [12.7mm] wider than the
afterset on all sides. Drill a 2 1/2" [64mm] diameter hole
over the center of the duct to determine depth of
concrete if depth is not known. Set saw to depth of
oncrete and cut opening for the afterset.

Step 4. Using a 2 1/2" [64mm] diameter hole saw, drill opening
in center of duct. For two- and three-gang, use template
for proper center locations.
NOTE: Holes in No. 4 duct will not be located in
center of duct. Center of holes must be
4 1/8" [105mm] apart.
Step 5. Complete installation by following Steps 6-9 on page 2.
PRE-POUR INSTALLATION:
Step 1. For single preset: Mark a center line down the
iddle of the duct and mark location for preset.
