Product Description

Windows and doors that slide open are a favorite entry point for criminals. They open & close silently and factory-installed locks & latches are often easy to defeat. This simple and reliable lock grabs onto window or door track and prevents further opening. Also lets you set maximum window-opening size - a great way to safeguard upper-level windows for children.
