DUCT CONNECTORS

The duct connector is designed for use on ducts down to
12" in width. When using the connector on smaller width
ducts, there will not be sufficient clearance to bend the tabs
on two sides of the duct connector.
In such cases the tabs may be attached to the sides of the
duct by using sheet metal screws or other suitable fasten-
ers. Holes for sheet metal screws are provided in three (3)
tabs on each side of the duct connector. If more than 3 tabs
B
need to be used to provide a more secure and air tight con-
nection, the remaining tabs can also be fastened to the
duct with screws after drilling the required screw holes.
If tape is used to provide a better air seal, it should be a type
approved by the applicable national or local codes.
