How Effective Are Sash Locks for Enhancing Window Security?
Sash locks are a popular choice for enhancing window security, especially for sliding windows, due to their design and functionality.

Pin locks are an excellent supplemental option, especially for vertically sliding windows, as they are simple to use and highly effective at preventing unauthorized access.
Slide bolt locks are particularly robust, as they prevent the window from being opened even if the sash lock is compromised.
