Frequently Asked Questions
How do window pulley seals stop drafts?
They cover the pulley weight openings inside older double hung window frames, which are a common source of air leakage. By sealing that opening, they block outside air from entering through the wall cavity.
Will installing pulley seals affect how the window operates?
They won’t interfere with normal opening and closing, but they will limit how far the lower sash can be raised. Expect about a 2-inch reduction in maximum opening height.
What’s included with each set of pulley seals?
Each pair comes with two seals, adhesive foam gasket backing, and Phillips head screws. Everything needed for a secure installation is included in the package.
Are these pulley seals easy to install?
Yes, installation is straightforward. The adhesive backing holds the seal in place while you secure it with screws, making it a quick upgrade for older windows without specialized tools.
