Product Description

Product Description

The Defender Security U 9858 Sliding Patio Door Lock Pins are designed to lock a sliding door into closed or ventilating position, and they operate with a simple insertion of their pins into a retaining ring to help prevent unwanted sliding of a door panel. Each lock is constructed of hardened steel pins that protrude past the inner door panel and extend into the secondary panel to lock an active door into place. A pin holder bracket is also included for easy storage when not in use. These locks help to prevent prying and lifting of the active panels, significantly reducing the chances of entry from the outside, and they can also be used on both vertical and horizontal sliding windows. Installation hardware and instructions are included, and they can be installed with a few simple tools.

From the Manufacturer

This locking pin is constructed from case-hardened steel and comes plated in chrome. The pin stores in its holder when unlocked and locks into the retaining ring when engaged. Securely locks your door in a closed or ventilating position.

Strong and works as we hoped for doggie door

Strong and works as we hoped for doggie door
We actually purchased this to use as an extra security measure for our doggie door. We realized that an adult could probably fit through it if they removed the cover and it made me a little nervous. This is a great solution because the door cover cannot be lifted with the pin inserted.
