This sliding door lock is designed to solve a common issue with pet door setups. When a panel insert prevents your original lock from engaging, it creates a gap in security. This lock restores that missing function by creating a new, fixed locking point directly on the frame. The steel construction provides a solid, reliable hold that keeps doors and windows from shifting or being opened from the outside. Once installed, it maintains consistent pressure, helping ensure the door stays firmly in place. Installation is straightforward and uses included hardware to anchor the lock into the frame. It can be positioned at the top or bottom depending on your door configuration, allowing it to adapt to a wide range of setups. Designed to blend in with your existing door frame, the low-profile look keeps your setup clean while adding a meaningful layer of security. It’s a simple upgrade that brings confidence back to your sliding door without interfering with your pet door’s daily use.
