KS Hardware Adjustable Door Sweep is a new Patent Pending product that is specially designed to maximize the weather seal between the house and the outside. The Double Bubble technology is proven to provide a tighter seal than the old multi-fin sweeps. Our sweep also come with a punched drainage channel to ensure any water that falls into the sweep is drained out and away from the house. Our combination of double bubble and multi-fin are guaranteed not to tear under normal use. The white screw cap can be painted or stained to match the the color/finish of your existing door.
