Double Wall Pipe Connector

Double WallPipe Connectors from Sheet Metal Connectors, Inc. are fabricated using a fitting size coupling that slips inside the mating pipe sections, as shown. A stop bead runs around the middle of the coupling to center the coupling in the connection. Secure the connections by installing sheet metal screws through the outer shell of the duct, 1/2″ from the stop bead.
