To cut and install an R6 ducting, follow these steps:

1. Measure and Cut the Duct:

   – Determine the required length of the duct for your installation.

   – Use a steak knife to completely cut through the duct’s jacket, insulation, and core. This process is straightforward and allows for a clean cut.

   – Once you’ve cut all the way around, use wire cutters to sever the wire that connects the two pieces of flex duct.

2. Prepare the End for Connection:

   – Peel back the jacket and insulation to expose approximately 6 inches of the core.

   – Slide at least 2 inches of the core over the fitting you are attaching to, ensuring a secure base for the connection.

3. Secure the Connection:

   – Seal the core to the duct collar with at least two wraps of duct tape.

   – Use a screw clamp or draw band to secure the connection tightly over the core and the taped joint. Make sure the fastening is tight to avoid air leakage.

   – As an additional measure, you may choose to use either a screw clamp or draw band in combination with the duct tape for added security.

4. Finalize the Installation:

   – Pull the insulation and jacket back over the core to cover the exposed area.

   – Use at least two wraps of duct tape to secure the jacket in place, further ensuring an airtight seal.
