Add locks or latches to your windows to make sure they stay closed.
Sliding Window Locks
Keep sliding windows from opening with these locks. Install the lock in the window track, slide it in place behind the window, and turn the thumbscrew to hold the window in place. They can be used to keep sliding windows completely closed or partially open.
Rotating Sash Locks
Turn the handle on these sash locks to keep closed windows from opening, and turn the handle the other way to allow the window to be opened.
Keyed Sash Locks
Secure closed windows by turning the handle on these sash locks. Then use the included key to lock the window so it can't be opened without the key.
Use these latches to lock windows or shutters that have two panels that meet in the middle when closed. They include a mounting plate for each side of the window and a bar that connects them.
Rotate the button to lock screens and storm windows in place, and turn the button the other way to remove them.
