Convenient, keyless
Universal additional security for easy locking without a key. Do you want to securely lock your aluminum, wood, or plastic windows while also valuing simple installation and convenient operation? This additional security is the solution. The lock is attached to the window frame without drilling into the window sash. Opening and closing are done entirely without a key. The solid steel bolt locks into place automatically. To secure windows and patio doors, the angle is manually flipped down, and then flipped back up to open.
