This 2-pack of dryer vent clamps secures the vent hose to the dryer outlet and the wall/vent hood. A tight connection helps maintain airflow, reduce lint leaks, and keep the duct from slipping off during use.

• Tightens around the vent hose to hold it securely to the dryer exhaust collar or exterior vent
• Helps prevent hose detachment, air leaks, and lint escaping at the connection
• Supports proper exhaust airflow by keeping connections sealed and stable
• Common symptoms pointing to replacement: hose won't stay on, visible gaps or lint around fittings, rattling at the vent, or longer dry times from poor ventilation

• Disconnect power; for gas dryers, shut off gas supply before moving the appliance
• Slide a clamp over the hose, seat the hose fully on the collar, position clamp over the fitting, and tighten with a screwdriver or nut driver
• Do not overtighten; avoid crushing thin foil ducting; ensure the hose is straight and not kinked
