Moisture exhaust duct sections on a dryer are held together using which method?

• A. Duct tape
• B. Metal screws
• C. Glue
• D. Locking bands

Answer: (D)

Joints in a dryer’s moisture exhaust need a fastener that stays secure, creates a smooth interior path, and resists heat, moisture, and vibration. Locking bands clamp the duct together with a tight, metal-to-metal seal, keeping the seam closed and preventing leaks of moist air and lint. This method also stays secure over time and makes cleaning easier, since there are no adhesive or protruding fasteners to trap lint. Duct tape and glue break down under heat and humidity, leading to peeling, gaps, and leaks. Screws can hold sections but may loosen, leak over time, or create rough edges that trap lint. Locking bands avoid these problems by providing a durable, simple clamping method that maintains a clean, continuous interior surface.
