Eliminate Drafts & Reduce Energy Bills – Tired of feeling chilly drafts in the winter or losing cool air in the summer? DRAFTeeze™ creates a tight seal installed on the crescent lock on single or double-hung windows, dramatically reducing air leaks and helping you maintain a consistent indoor temperature year-round.

Custom Fit for Crescent Locks – Designed specifically for windows with crescent-style sash locks, DRAFTeeze™ fits snugly inside the locking mechanism, sealing the common gaps where air escapes.

Fast, Easy Installation – Installs in 10 seconds.

Discreet Protection – Our low-profile design blends seamlessly with your window crescent locks. Get powerful insulation without bulky weatherstripping or unsightly plastic film (both of which will damage your varnish and or paint when removed).

All-Season Comfort – Whether you're battling icy drafts in January or trying to keep the AC from escaping in July, DRAFTeeze™ works in all climates. One product. All-year performance. Re-usable for window cleaning and reinstalling year after year if you choose to only install them during the winter, summer or both seasons.

Durable & Long-Lasting – Made in the USA with materials that allow flexibility and long-lasting durability.

Universal – Shim Step design supports a wide variety of gaps, to work with decades of supported windows.
