Table 2. Duct Connector Sizes
Standard Duct Connector Installation
The standard duct connector is designed for use on ducts
12” in width. NOTE: Ducts narrower than 12” may not
allow sufficient clearances for this type of installation.
See Narrow Duct Connector section.
1. Center the duct connector in the floor opening with
bottom tabs resting on top of the supply air duct.
2. Mark the cut-out area on the supply air duct by tracing
around the connector tabs of the duct connector. See
Figure 8 .
3. Remove the duct connector and cut out the marked
area of the supply air duct 1/4” larger than the actual
cutout drawn.
4. Install the duct connector back in the floor opening with
the bottom tabs extending into the supply air duct.
5. Install the mounting plate ( Figure 8 ) under the back
side of the duct connector. Align the screw holes in both
components.
6. Secure the duct connector and the mounting plate to
the wood floor with appropriate size screws.
7. Bend the connector tabs on the bottom of the duct
connector upwards and as tight as possible against
the supply air duct. See
Figure 9 .
8. Seal all connections with industrial grade sealing tape
or liquid sealant.

Narrow Duct Connectors
This attachment method should be used if there is
insufficient clearance to bend the tabs on a standard 12”
duct connector.
1. Score and cut the top of the supply air duct as indicated
in Option 1 or Option 2 ( Figure 10 ). With Option 1 choice,
cut out the metal from the shaded area.
2. Fold the two flaps (Options 1 or 2) up to form the opening
for the duct connector.
3. Install the duct connector with the bottom tabs extending
into the supply air duct.
4. Bend the tabs on the bottom of the duct connector
upwards and as tight as possible against the supply
air duct. See
Figure 11 (page 11) .
5. Form the flaps (Options 1 or 2) up against the duct
connector as tight as possible.
6. Secure the duct connector flaps to the supply air
duct with staples (3 minimum) or if a 2x block/joist is
not provided, use sheet metal screws (2 minimum).
NOTE: The duct connector tabs may be attached to
the air duct with sheet metal screws or other suitable
fasteners as long as the duct connector and the air duct
are securely attached.
7. Seal all connections with industrial grade sealing tape
or liquid sealant.
NOTE: Requirements for sealing ductwork vary
from region to region. Consult with local codes for
requirements specific to your area.
