Draft Blocker - Installation: Dundas Jafine

Dundas Jafine’s Draft Blocker helps to prevent cold air from entering the home through the dryer duct. This product is molded from high impact plastic and fits all 4” ducts.

Does this really work we have a leak probably because the outside flapper vent never completely closes.

Can this be installed vertically rather than horizontally? I bought one but I have rigid ducts and can only install this after an elbow that comes out of the foundation wall and down to the laundry room.

I can not commit on the reason for the leak but as far as this product goes, It definitely prevents backdraft and cold air from flowing back into your vent and vented space,

My vent pipe to the exterior is inside my finished ceiling and not accessible. Can this device be installed immediately at the dryer outlet instead? Or will the plastic melt?

This product should not be attached directly to the dryer exhaust port
