Window sash locks fasten window sashes together or to a window frame in order to prevent entry into a home through an unsecured window. Sash locks may be used on double hung, single hung or casement windows.
Choosing Keyed or Keyless
Window sash locks may use either a key or a simple flip mechanism. Keyed locks are harder to force open, but the extra security comes with a higher price tag. For safety, keep the key near the window for an emergency evacuation.
Keyless window sash locks are inexpensive, often five dollars or less at hardware stores. Determined intruders find keyless window sash locks easier to force, though any type of lock acts as a deterrent to most opportunistic burglars. Keyless locks eliminate the concern that window security measures can impede emergency evacuation.
Window sash locks come in a variety of materials, such as brass, zinc, steel and vinyl. Solid metal window sash locks are more durable than vinyl ones. Metal locks may be powder coated or metal plated and come in a variety of colors and decorative finishes to match a room’s decor.
