Imperial Draft Blocker, 4 in Duct, High Impact Plastic

Helps keep cold air from sneaking in through the dryer duct.

Fits all 4" ducts with a plain, no fuss setup.

Product Overview:

If you have a draft where you do not want one, this draft blocker gets right to the point. It fits a 4" duct and helps keep cold air from slipping back into the home through the dryer line. The molded high impact plastic feels solid in hand, not flimsy, and that matters when you want a simple fix that holds up. Put it in place and the space starts to feel steadier, less sharp around the edges. It is a small part, sure, but it does a tidy job.

Key Features:

• Fits 4" ducts: Made for all 4" duct openings, so you can match it to the setup without a guessing game.
• Blocks cold air: Helps stop outside air from pushing back through the dryer duct, which can make the room feel drafty and off.
• High impact plastic build: Molded from tough plastic that feels dependable, with a clean, practical finish that does the job quietly.
• Simple fit and use: Straightforward enough to set in place without turning it into a half day project, which is a relief.
• Compact size: At 4", it keeps the profile small while still doing useful work where the duct meets the home.
