consist of the following:
1. DM-S Saddle (1)
Supplies Not Included
- 4.5-inch hole saw or snips

Standard Installation
Step 1. Cut Hole
Find an appropriate location for the DM-S and cut a 4.5” hole.
Step 2. Prepare DM-S
Slide the cable ties or band clamps through the saddle eyelets.
Select band clamp or cable tie length that corresponds to the duct size.

Length

Step 3.
- Lay the saddle against the round duct and connect the cable ties or band clamps around the duct.
- Tighten the cable ties or band clamps until the foam gasket is slightly compressed against the duct wall.
You can pre-bend the saddle for smaller duct work if needed.
Step 4.
- Turn the DM-2 counter clockwise from the final installation orientation and insert into the saddle keeping in mind
the airflow direction.
Step 5.
- Rotate the DM-2 clockwise until you hear a click and the connection feels secure.
Pull back lightly on the device to ensure proper installation.
Alternative Fastener Installation
- Install fasteners in locations shown below.
- Use #6 X 1” self-piercing sheetmetal screw.
- Once secured, continue at Step 4 to complete installation.
If duct surface is irregular and the DM-S does not form an adequate seal, additional fasteners may be used.
