Anderson Pulley Seal

Stop Window Pulley Drafts

An important source of air leakage in older homes is the pulley openings in your double-hung window frames. (you can easily feel the draft with your hand on a cold day). The Anderson Pulley Seal permanently stops this draft without affecting the operation of the window*. They are easy to install using the adhesive foam gasket and screws provided.
