Drafts can enter a house from the wall cavity through the pulley holes in the window frame of double hung windows. Pulley seals are designed to fit snugly over pulley weight holes of older double hung windows to eliminate the draft. Each pair consists of two seals with an adhesive gasket backing and Philips head screws.
Note that the pulley seals will reduce the amount the lower sash can be raised by about 2 inches.
