Defender Security U 11316 Swing Bar Door Guard — High Security Thumb Turn, Satin Nickel

Enhanced Entryway Security with a Clear View

The Defender Security U 11316 Swing Bar Door Guard combines practical safety with thoughtful design. In everyday use, you can crack the door just enough to see who’s there, while the satin nickel finish adds a modern, understated look to your entry. When engaged, the mechanism interlocks a ball on the keeper with the bar lock, creating a sturdy barrier that helps deter forceful entry without obstructing routine door checks.

This model goes beyond basic guards with a backup thumb turn security lock. The release tool is blocked, increasing peace of mind when you’re home alone or traveling. In emergencies, the thumb turn can be released with noticeable force, allowing quick access while preserving security during normal use. After release, the unit still functions as a traditional swing bar door lock, and an Anti-Lockout emergency access tool is required to swing the guard out of place. For best results, engage the backup thumb turn whenever you’re not actively using the door.
